Good morning everyone! I have a 2000 Yamaha ttr250 that I recently acquired from someone that knew nothing about proper maintenance of anything mechanical I noticed the rear shock is very soft on my bike even with the remote damper dialed all the way up to the stiffest settings. I also noticed lots...

Every now and again I get a "First time I have seen that!" moment and that happened recently when I was replacing a weepy cylinder base gasket on a friend's engine. Having removed the cylinder bolts and started to move the cylinder some emulsified oil (with water droplets in it) dribbled out! Blow me d...

Due for a new rear disc, the shop lists 3 different ones. Apart from bling levels is there any difference in them?

I just purchased one of these today, so should arrive a 2-3 weeks from the US I don't have enough strength in my wrists to fit a D606 rear tyre, I can do the front, but the back, just can't manage it.

Here's an odd one to ponder: I have a Koso digital speedo on one of my ttrs. Battery memory/backup, but powered by the old ignition switched live feed that went to the original speedo (Open Enduro - digital) The way it works is when you turn on the ignition, it powers up the backlight and display. Also pow...

Hi all, I have pulled the carb out recently on a 2007 TTR250. I have seen a couple of pictures where people have said there is 2 O'Rings under the cover of where the diaphragm and needle are. Is this true for my model? As when I pulled it apart, none fell out. Perhaps they have perished completely? Tim

Does anyone know if applying plasti dip to a cracked carb diaphragm will work to seal pressure? I will eventually replace, but I just spent $75 on carb rebuild parts and don't want to spend another $35 just yet. I assume it would be best to apply to underside of diaphragm due to the suction. Does gas c...

Hi guys, I am not very happy because I hardly can find anything on the internet for my 1995 Open Enduro. I hope I won't regret buying this old bike. There are parts for later models (1999 upwards) but nothing for old TTRs. My question is are the fork gaiters the same on '99-08 models as on my 1995's? Could I...

Hey Guys. I have been having a whole plethora of issues with my bike, but knocking them out one step of a time. Most recent, I replaced the float, and float Needle valve assembly, since the carb was overflowing fuel when I would turn the fuel on. That issue is solved now. But now my issue is that the bike wi...
