naw i just mainly work on my own stuff. spent the last couple years aquiring nearly every hand tool you can imagine and alot of specialty tools and full set of professional porting tools. dont have a mill or lathe yet but been looking around for some decent older used ones. problem is the grarage aint really big enough for more stuff unless i kick the gf out . might build a 12x10 shed in the backyard this summer to hold more equipment

wish i had some money for a dyno. valuable asset for checking your progress is heading in the right direction. anybody know what a older used dyno goes for ?

you normally get a 1 or 2 trips in before memorial ? ill probly be there memorial but want to make it atleast 1 or 2 times before then

i think theres alot of bad info floating the web from misinformed people. ive seen potential do-it-yourselfers on other forums ask how to get into doing their own work and the usual answer they get is they will just screw it up if they try so just send it off to some shop. most stock cylinders from any manufacturer are in such a high state of inefficiency and low tune that a guy would have to be dumber than a fence post to screw it up to the point it ran worse than before. from my experience, the guys that cant change a spark plug without stripping the threads are the ones discouraging others from doing their own work. when you dont know anything its amazing how fast you can learn because nearly everything you read and hear and see will be new gained knowledge, assuming your sources of information are credible.

anybody around here do their own porting ? been to alot of sites and its rare as 4 leaf clover finding people who do their own grinding. be cool to hear from some peeps that work on their own stuff like myself

normally i dont worry about the side play unless its overly excessive. up/down play, how much arc the small end swings and if the rod twists is mostly what i look at.

vp site has all the specs for their fuels. however they talk in compression ratio terms and not kicking pressure

whats the import grey ? is it the permatex ultra grey with the motorcylce on the package ? says that stuff fine for gas and assembling engine cases

i didnt want to say anything and have stones thrown at me but ive used rtv for quit a while with no prob, not on banshees specifically but my other 2strokes. maybe i just been getting lucky . its hard to say

if you look at rtv data sheets it says retains effective properties when in contact with motor oil ,tranny oil and alcohol

should check out thumper talk sometime. some real dumb MOFOS there. they beat out cranks with a hammer. seperate cases with screwdrivers and chisels. and some dipshit put rope in the spark plug hole to stop the piston so he could loosen the crank gear nut. problem is the piston was too far down and some of the rope went into the exh port and when he turned the crank gear nut the rope got wedged between piston and cyl wall. he probly still scratching his head how to get that rope out

i tried that honda bond4 one time and threw the tube away. runny, messy, stringy crap. seems like the tube says not to use on gasket less applications. either way, good luck if you use it. i hate the shit. been using ultra balck permatex for a long time and it works great for me

you talking sand mnt ? ill be heading that way when i get my bike back together. probly be another 4-6 weeks

ive seen shattered ceramic crank bearings so i personally wont use them anywhere in my engines. check out skf explorers. theyre supposed to be one step better than a normal bearing. ive got some in my engine SKF Explorer bearings – the new performance class from SKF SKF Explorer is a new performance class of rolling bearings, of the types deep groove ball bearings, angular contact ball bearings, cylindrical roller bearings, tapered roller bearings, spherical roller bearings, CARB toroidal roller bearings and spherical roller trust bearings, which provide a substantial improvement in key operational parameters relevant to the bearing type and its typical applications. This new level of superior performance represents the blending of SKF’s applications knowledge with its expertise in tribology, materials development, design optimization and manufacturing. Using advanced analytical and modelling techniques and supporting testing, SKF engineers were able to confirm that SKF Explorer bearings provide a significant improvement in key operational parameters. These parameters, according to bearing type and application, include noise, vibration, service life, dimensional stability, dynamic load carrying ability and heat generation (frictional moment). Because these parameters are not adequately factored into standardized life calculations, SKF Explorer bearing life is calculated with modified factors, which takes key operational parameters into account. SKF Explorer bearings are fully interchangeable with previously specified SKF standard bearings of the same type and size. These bearings are included in the relevant product tables and are easily identified by an asterisk (*) after the bearing designation. The making of an SKF Explorer bearing Achieving the outstanding levels of SKF Explorer bearings has only been possible due to the basic sound engineering design of SKF products and by further improving the manufacturing of bearings to these designs. By studying the interrelationship between each bearing component, SKF engineers were able to maximize the effects of lubrication and minimize the effects of friction, wear and contamination. To do this, an international research team looked at each component at micro level and then developed new procedures to consistently manufacture this new standard of excellence. SKF Explorer bearings are characterized by a number of technical improvements, some of which are listed below. Depending on the type of the SKF Explorer bearing one or several of these below given examples have been applied: Improved bearing steel SKF Explorer bearings feature an extremely clean and homogenous steel with a minimum number of inclusions. This improved steel is so much cleaner than the highest grades covered by present classification methods that SKF has developed new calculation methods to take this factor into account. The unique SKF heat treatment procedures To maximize the benefits of SKF’s ultra-clean steel, engineers incorporated unique heat treatment procedures. These new procedures optimize the bearing’s resistance to operational damage without affecting heat stabilization. Wear resistance was improved so dramatically that SKF engineers were not able to accurately predict life expectancy using existing life factors for calculation methods. Improved surface finish The surface finish on all contact surfaces (rolling elements and raceways) has been improved to maximize the effects of the lubricant and reduce vibration and noise levels. This has lead to a smoother, cooler running bearing that uses less lubricant and consequently the arrangement, including the seals, requires less maintenance.

was just messin around. i dont know anything about the 4stroke stuff. could be a good runner for all i know

i would demand a refund if my 900cc had only 100hp

whats a clutch boss ?

dont know what tools you have now but if you dont have any then keep a eye on ebay. should be able to find a nice used foredom unit with straight hand piece for good deal. right angle hand piece is alittle harder to find used and their pricey to buy new but i would just keep looking

been a few years ago but i sent 3 jugs to different so called professional shops. one looked and ran good. the other two were garbage. decided i wasnt going to pay for dogshit anymore and bought my own porting tools. havent looked back since. alot of halfass shops now days getting rich and sending crap out the door. when the rubber meets the road its easy to see which ones dont know their head from ass

might get some extra oil on your top rod bearings which is never a bad thing but im not sure youll see much increase in power

hard to tell but i didnt hear any strange noise that would be associated with the gears. but anytime you have gears like that you may experience a whine. vehicle trannsmission and transfer cases do it to some extent and a engine using gear drive timing do it pretty loud. you can hear in this video

ya i think it was cheetah heads now you mention it. just remember reading about it but couldnt recall exactly which heads. like you said, still makes a guy second guess the rest of their stuff lol

ive never dealt with trinity nor do i plan to but ive read several times on other forums they screwed up heads by cutting reverse squish angle. not sure if they did that to alot of heads or just a few but might want to check those domes before installation

30mile east from rock springs. 22 miles of it is dirt road. its usually chopped up from the oil field fuck heads and the fat ass lazy county workers rarely grade it. sand mnt utah is 100x better if you ask me. and probly closer to you

just be sure to use koyo cuz theyre the bestest . but really i got skf still going fine that are probly older than some of the members here
