I got a 38mm keihen, i need a 36mm, anyone feel like trading?

 

why? i got a stock one. ill trade, i belive it is a 34mm

 

i also have a stock one, i wanted to go bigger to get the most out of my mods, but i got a hell of a deal on this one, and i was just told its to big unless i port, and i don't have the extra cash right now for that.

 

You've been told??? Or did you try it and cant get it tuned?

 

it should come tomarrow by ups. Needar told me it was too big for my bike, y , what do u think?

 

With a 2 stroke, I'd think a 38mm carb would be fine. Now, a 250 FOUR stroke, that'd be over carb'd, in my humble opinion.
Your bike will probably idle rougher than you're used to, but it should RIP at top end. Just take some time to jet it right.
Do some research, check out what other guys are using on 250 2 strokes. Do a search on the forum.

 

thanks man, maybe i won't get a smaller one then, any clue on what kind of reeds I might want then, i want something to fit the stock cage.

 

These are all quotes I found by searching "lt250r" and "carb"

tried both Mikuni and Keihin on my 87 LT250R and the best carb i found was a ESR Mikuni TMXx 36mm. Starts great and runs like a champ, with easy jet changes. I know a lot of people that love there Keihin, and I know they are good carbs, but don't count out the Mikuni. If you go with a Keihin stay away from the PJ's...they idle like %$#%.

The 38mm Mikuni works real good on mine too. It screams from start to finish, nice and smooth powerband. You also can get them for 50$ or so on Ebay.

I have a 38mm Mikuni Flat Slide, and it works great. And yes, it does make a big difference, especially if you do get P&P in the future.

If you are going to Port and Polish your motor in the future dont screw around with those little carbs get a Keihn 39mm PWK and be done with it 38 PWKs are good too PJ's are junk
MIKUNIS ARE JUNK they bog if you do any type of racing like for instance MX or SX it cant take the whoops and big jumps you could use a PC RACING carb vent system but that only works a little.

 

Is the 38mm carb you are talking about that PE that is in your description. If so, those carbs arn't worth much. They are old and out dated. You want at least a PJ, and preferably a PWK. Round slide carbs aren't as good as flat side carbs

 

Hey AKSAFARI, I just bought a 38mm Flat Side Keihin carb for my '86 TRX250R. It's 30 over with a CT pipe Pyramid Reed Force Valves and I've got the airbox lid removed. You sound like a man who knows jetting so what jet would be a good place to start to fine tune my bike? Thanks!
