Now it has a bad bog mid throttle. Just looking for good replacements instead of buying another stock one for $40...

Fast Idle Speed Adjustment (ie Choke)
(Preview)
Hi all, I have the white tank TTR250 Open Enduro, I believe 1994ish. Since I've bought it, it has an annoyingly fast idle speed with the choke on. I have the manual but I cannot see a section which describes how to adjust it. Any help would be appreciated! For reference: I tried turning it in, but it doesn'...

The effect of storing a tank with fuel in
(Preview)
I had put a spare tank on my 325 to use whilst I put a new set of decals on the original. The tank had a new fuel tap on so I didn't bother to take it out for inspection. I actually got around to stickering up the original tank today so decided to drain the spare tank of fuel before taking it off. It seemed odd that...

Jetting help with 1996 Raid
(Preview)
I have been playing with jets on my 1996 Raid lately. My bike has the snorkel out, no restrictor. Before it ran fine, but the first 1/4 was weak so I changed the #50 pilot to a 52.5. The new power was instantly noticeable. However, beyond about 1/4 -1/3 it weakens for a bit, then picks up again. Every singl...

wont idle without some choke
(Preview)
I was given an 04 TTR by a good friend. It hasn't run for a few years. I started it a few weeks ago and it kept cutting out. Because of the long lay off I suspected carb issues. I have removed, stripped and cleaned the carb but used no new o rings etc. I'm pretty sure somebody with a heavy wrist has had a go at the c...

Possible carb replacement ?

Wonder how well a xt250 carb would fit ? The cables look like they would be a straight fit and it's a pumper carb like the original. The Teikei carb seems to be getting very rare so could this be a good replacement ? Being Mikuni spares would be available and iv'e seen service kits on ebay. Think i'd give one...

Jetting reccomendations, running rich
(Preview)
My bike is running rich, as it splutters a lot on WOT. I have ran it with air box lid removed and it runs a lot better. Main jet is a 147, can anyone recommend what size main jet to change to? exhaust is a CRD open pipe. Is there a point changing pilot jet as it runs ok on low revs. Many thanks.

Hello, I'm just learning how to take apart my carb on my TTR, as I cleaned the jets after it sat all winter. When I put it all back together and turned on the pet**** to fill the bowl, it started leaking out of the overflow. I figured the float was stuck so I tapped on it and it stopped leaking. Then when I st...

As above, my TTR starts and idles very well, i can even get it to idle very slowly and it ticks over lovely. But just above idle it seems slightly hesitant, this will be a pain when riding off road. Other than this it revs cleanly through the rev range as it should. Iv'e put the standard exhaust back on incas...
