kotin6 Posted July 31, 2006 Report Share Posted July 31, 2006 Ok so I found out why my shee died and wouldnt start back up. It was compression. I pulled the cyliinders to find them both scratched pretty good twards the front of two blown pistons. This is the second time this has happen to me on fresh rebuilds and I honestly think I am maybe puttin the rings on incorectly or something. I think the jugs are an easy fix with some honing or if someone want to get them bored bigger what ever. I put them on eaby. I am looking at getting a set of cubs. The only thing is I dont want to stroke my motor. I see all theres cubs for sale that say I can use my stock reeds and head and all that. Well I dont have stock reeds, head, pipes, intakes, carbs anything really. So what I am wondering is if I do buy the cubs (65 bore stock stroke) will it work with my mods I have listed in my sig? I know there are some builders on here like Jim who did my port work, and I would greatly apriciate their and anyone else who actually knows what they are talking abouts openion. I am trying to get back on the road (literaly ) as soon as possable as it has now been in a friends garage for about 7 months and I feel bad. thanks Quote Link to comment Share on other sites More sharing options...
dajogejr Posted July 31, 2006 Report Share Posted July 31, 2006 Everything will fit just fine. Take it from me, the pipes you have will hold you back a little. You can sell your stock cylinders and your stock crank for a few bucks which help recoup some of the cost. IF you decide to use your stock crank, I'd have it welded, and I'm sure Jim at Passion does a great job on that. And, I've have some heavy duty bearings put on it as well. What they mean by bolt on is...if it will bold onto your stock cylinders, it will bolt onto the cubs...they're not neccesarily talking stock parts. Unless Jim did a 12 port on your stock cylinders...or a major drag port, simply bolting on a cleaned up cub will make a noticeable difference. The cub from the factory needs to be cleaned up. There are flashing and casting flaws that need a quick cleaning...other than that...the porting is awesome on them out of the box. Quote Link to comment Share on other sites More sharing options...
Bansh-eman Posted July 31, 2006 Report Share Posted July 31, 2006 word.. how ever your not going to get the max potential out of that baby if your not going to stroke it... is there any specific reason why you dont want to stroke it?

kotin6 Posted July 31, 2006 Author Report Share Posted July 31, 2006 word.. how ever your not going to get the max potential out of that baby if your not going to stroke it... is there any specific reason why you dont want to stroke it? As I said I think the reason i have blown it the last 2 times is maybe I am putting the rings on the pistons wrong. I am stationed in Italy and have to do all my own work on the shee. I am NOT an experienced mechanic. I really dont want to get in to splitting casses and stuff. i just want to ride. I have so much money into this thing already that I cant see taking it back to stock. So I figure I can get the cubs and when I move back to the states I am moving to New Mexico. If I want to stroke it and port them I can always have it done when I am in the US. It is not cheap to ship a motor back and forth. I have moved much closer to base now so when I ride to work the trip is not as long and I think if I can kind of baby it till I get back to the states I will be ok. also how much does it usaly cost for the clean up on the cubs?

dajogejr Posted July 31, 2006 Report Share Posted July 31, 2006 also how much does it usaly cost for the clean up on the cubs? Ask the builder buy it from, it'll range in price...from free to a few hundred bucks. Quote Link to comment Share on other sites More sharing options...
kotin6 Posted July 31, 2006 Author Report Share Posted July 31, 2006 Ask the builder buy it from, it'll range in price...from free to a few hundred bucks. Im thinking somewhere closer to free would be better lol. Where did you get your cubs? Quote Link to comment Share on other sites More sharing options...
bkabina Posted July 31, 2006 Report Share Posted July 31, 2006 I have seen the pictures of your jugs on e-bay.I don't think your problem is from installing the rings wrong,It is hard to tell in the pictures but it almost looks like they scuffed because the warm up period was to short.Almost like a cold seizure.The pisons got too hot too quick and the cylinders were to cold and your tolerances got to small.The exhaust port could maybe use a little more chamfer as well. What oil and mix are you using? Quote Link to comment Share on other sites More sharing options...
dajogejr Posted July 31, 2006 Report Share Posted July 31, 2006 Im thinking somewhere closer to free would be better lol. Where did you get your cubs? I bought my whole motor from Jeff @ Fast. cubs, pistons, head, crank, clutch and a bunch of odds and ends. Normally, cubs go for 875 or so. Some will up that price a little...but include a clean up port. I don't think I'm going out on a limb by saying a clean up port can be done in about an hour or so... Whadda think Steve...depending on how bad the casting flaws are...about an hour sound right? Quote Link to comment Share on other sites More sharing options...
Animalman294 Posted July 31, 2006 Report Share Posted July 31, 2006 Man, you're stationed in Italy, how do ya like that and how long ya gonna be there? How do you ship your stuff back (ie. your shee)to the states, military transport or private shipper? Quote Link to comment Share on other sites More sharing options...
kotin6 Posted July 31, 2006 Author Report Share Posted July 31, 2006 thanks for the info and please keep it coming. I love Italy, been here 3 years, this is my first summer staying here instead of Iraq or Afghanistan. Am leaving but not sure when . Going to New Mexico. I may have to talk to fast. I run 32/1 mix, I never even got off the pipe when that happened to the cylinders. I never even hit the powerband. the motor never even had a chance to get warm really.

wesw Posted August 1, 2006 Report Share Posted August 1, 2006 I run 32/1 mix, I never even got off the pipe when that happened to the cylinders. I never even hit the powerband. the motor never even had a chance to get warm really. what kind of oil?? if you never got off the pipe you were in the powerband. a cub would be a good mid to top motor. if you want to get your motor going why dont you just ship it to jim and let him put it together and check shit out for you. easy way to solve any putting it together problems. but i think buds kinda right. ifyou bearly ran it. it didnt break in correctly to scratch the jugs up that much. or some awful oil was used.

BigRed350x Posted August 1, 2006 Report Share Posted August 1, 2006 Everyone is going to cubs! I can't wait for the new billet cylinders to get out on the mainstream market, I wanna see how they do! Cubs are the way to go. (for now) Quote Link to comment Share on other sites More sharing options...
kotin6 Posted August 1, 2006 Author Report Share Posted August 1, 2006 Any builder want to chime in on this? Or anyone else Quote Link to comment Share on other sites More sharing options...
bigboybanshee Posted August 1, 2006 Report Share Posted August 1, 2006 I kind of agree with bkabina, I remember hearing about your past two engine failures and I'm thinking there's something going on that's causing your problems. I would highly recommend trying to find the exact reason for the past two problems before going and spending the money on the cubs and having the same thing happen on a new set of cylinders. :shrug: What size carbs were you running with your old setup? I'm not trying to be rude, etc, this is just my opinion on what I would do if I were in your shoes. :beer: Quote Link to comment Share on other sites More sharing options...
kotin6 Posted August 1, 2006 Author Report Share Posted August 1, 2006 My first blow was due to running wot for about 10 minits on a daily basis to and from work over the ocurse of about 6 months. my 2nd i think was from having to small of carbs. I now have 33mm before I was running stockers. I looked at my pistons and im telling you guys the were only fucked up on the rings and that was the only part of the cylinder that was damaged. Im not sure of course but Im almost certing that it was a loose ring problem. Maybe not i dont know. If anyone wants to ship me some decent 2 cycle oil I can pay you via paypal . The only shit I can get over here is supposed to be good but it is used for scooters and dirtbikes. How do you think the shee would run with the set up I have listed and the cubs. would I need diffrent domes? will the cubs acomadate the studs for the cool head? will the work with my billet intake? I think I am going to give Jeff a call at fast racing. Quote Link to comment Share on other sites More sharing options...
