o2sandshee Posted June 28, 2006 Report Share Posted June 28, 2006 i got some t-6s for a good deal, put them on & shee ran tons better. i have .30 over barrels, 30mm pwks, vf3s, the t-6s & stock gearing. but got beat by a mild ported stocker w/ t-5s & stock carbs. the dude let me ride his bike & it pulled hard. confused? im not a beginner rider, no mis shifts.

Rebel3190 Posted June 28, 2006 Report Share Posted June 28, 2006 t-5s respond very well to porting,t-6s work best with stock motors. Quote Link to comment Share on other sites More sharing options...

2003LimitedBanshee Posted June 28, 2006 Report Share Posted June 28, 2006 Ported, hands down is the difference. Plus, no offense but you've basically got T6's going for you performance wise (plus the VForce 3's, but minimal). Those big carbs should be making little to no difference, in fact quite possibly hurting the performance, assuming you are running duals (pwks). Until, you allow that motor to breathe more, stock carbs will run strong, and there is no need for that big of a carb. A friend of mine who works at the local stealership put together a bike for his wife that turned out 82 HP on 2mm overbored stock carbs (28mm total). Plus, are you sure that is all he was running. Even if it was, I would expect to get beat, but he may have been running some additional timing, shaved head... some sort of coolhead? My guess is that if he has had it ported he's probably farther into the bike than it may have first appeared. Quote Link to comment Share on other sites More sharing options...
dajogejr Posted June 28, 2006 Report Share Posted June 28, 2006 You just learned a quick lesson why after new pipes and air filters, porting is the best mod...and why it costs a bit. After pipes, it makes ALL the difference in the world. As for the T6 vs. T5 debate, I don't buy it. I know on Toomey's site it says t5 for ported motors, and T6 for stock...but his jet kit also comes with 270 and 280 mains with pipes, no airbox/clamp on filters. I can tell you first hand that jetting from Toomey themselves is lean unless your at higher than about 3000ft of elevation. So...the common saying around here is T5s for porting, T6 for stock...but I've yet to see a dyno chart say different. Quite the contrary...I've read a few posts with people running T6 on ported motors and they run quite well.... That being said, I have T5s because I found them used and cheaper...flat out. I'd love to dyno a set of T6's to compare to T5s on my cub...anyone wanna send me a set?? :beer: :beer: Quote Link to comment Share on other sites More sharing options...

T6's only work work good on non ported motors, t5's will work great on all combo's Quote Link to comment Share on other sites More sharing options...
differentstrokes Posted June 28, 2006 Report Share Posted June 28, 2006 I had t-6's before too and I swapped to lrd rfx's (comparative to t-5's) when I decided to port and build my motor up a little. I haven't finished yet so I don't know the results, but I heard the same stock/ported motor debate and decided to go ahead and switch. I made a few calls to toomey and talked to the tech about what I wanted to do and he said bigger carbs hurt the t-6's, not to go over .30 on a head or less than 21cc on domes, and that bore size didn't really affect them that much. He said a mild port wasn't to bad, but messing with the transfers seemed to hurt the pipes. Call and talk to the guy, I think his name is James or ask to speak to the tech.

Animalman294 Posted June 29, 2006 Report Share Posted June 29, 2006 I'll will agree that the T-5's are a much better pipe than the T-6's on modded motors............. :beer: Quote Link to comment Share on other sites More sharing options...

00tbanshee Posted June 29, 2006 Report Share Posted June 29, 2006 like 2003limitedbanshee those big carbs are killing you i had a set of 34's on mine with no port and had no low end put the stock carbs on and was like a different bike plus i picked up 2 tenths in 500ft at the drags and im running t5's, love them id say get a set Quote Link to comment Share on other sites More sharing options...
dajogejr Posted June 29, 2006 Report Share Posted June 29, 2006 thanks for the advice, i will call the tech guys & see what they say. i have the stock carbs maybe i should just put them back on & jet rejet. While that would be free...it'd be going backwards in my opinion... I'd keep your pipes, look into getting a play port or mild port job, and leave those carbs on... If you were going to go all out...drag port, stroker motor...then yes, ditch the pipes...and get monster carbs.... Stock carbs, believe it or not...are pretty efficient for what they are. But once you go bigger...no need to go back. Quote Link to comment Share on other sites More sharing options...
o2sandshee Posted June 30, 2006 Author Report Share Posted June 30, 2006 im just trying to max out what i have till the season ends then its off to the machine shop. time for a real motor. lol. think ill get an adj timing plate, that should help. tired of getting beat by tired looking piles that came out of barns.

DirtyFitz Posted June 30, 2006 Report Share Posted June 30, 2006 This has always been a big debate about T6's and T5's. Best said that T5's are best for ported and worked engines and T6's are best for stock and lightly modded engines. I run the T6's and havent had a problem with them so far but then again my engine is lightly modded, I seem to like them but then again if I had another $500 to get new pipes they'd be something more top end aggressive since I strictly ride dunes.

You've got the banshee sickness... First it'll be porting, then top end pipes...etc. I understand...that being said, save your money on pipes for now... The simple bolt on stuff will be fine. If you can afford to, build a package instead of piece mailing it... A good builder can port into the pipes you bought.. In other words, you buy a CPI or Shearer pipe beforehand...and they can port your jugs to work best with that style pipe.... Quote Link to comment Share on other sites More sharing options...
ssanddemon Posted July 1, 2006 Report Share Posted July 1, 2006 I ran TR-6s on my mildly ported motor for a few years. I found that the bike had pretty poor bottom end and that it didn't rev up as high as the better flowing pipes did- I guess stock motors like a bit more backpressure. But it was OK, no big complaints. Decided to go with a set of PT Mids and I really like the change. Top end is about the same, it drops off about 10K; but the bottom is a lot stronger and dropped the start of the powerband down by about 2k- the whole motor feels better. My rationale on high revs is this anyway- I don't need to rev to the moon, I can keep hitting the band in the next gear, and the next...and the next...
