i weigh 12 stone and ride mostly on road, is there a recommended suspension setting? if not what is the best method of achieving the perfect balance? i guess a special (shock) pump will be required for the front fork spring rate?

Ok, so vice grips, torch, and every other technique did not work. Here is a pic of the aftermath, now the bottom stud hole broke on the bottom side is there any way to have this welded, drilled and tapped?

My TTR oil plug was a NIGHTMARE to get out. When the dust all settled it was ruined. I hate the soft metal it was made from so I bought a plug at my auto store. It was really nice, solid steel and 17mm BUT it was about a 1/4inch longer. I was concerned about the extra length (thats what she said) hitting somethi...

G'day All, my ttr has developed another oil leak. I fixed the usual one on the head with a plug from Brian. This is messy and leaves a spot every time I park it

Hello everyone here. The spare parts I ordered should arrive by Tuesday. I was re-reading the service manual and come across LUBRICATION question during motor rebuild: On some points it is advised to use "Molybdenum Disulfide Oil" , on others "Lithium Soap grease". Some...

No parts available where I live, no any usable mail service. I am going to be in the USA for a couple of weeks in Nov and thought I'd order some parts online and have the mailed to my friends in Virginia. So a question to all the US TTR riders,can you suggest an online retailer I could order from. I need clut...

Can anyone help me with my thought process please... I've taken the head/barrel off and refitted to cure an oil leak from the bottom of the barrel at the front. Now it's all back together it runs as rough under load as you like. Idle is fine, steady throttle is ok but not brilliant but acceleration is jerk...

Ordered a new idle set screw from Yamaha. Lo and Behold, it is on national backorder, mine broke as I was attempting to adjust as this bike has sat in the elements to my suspicion, for quite some time. I'm going to pull the carb and drill out the original. Does anyone happen to know what pitch and thread si...

Ok, so I finally got my bike running. Upon the throttle sticking after running it a few times I decided to inspect it further. I pulled the carburetor and noticed a super sticky brown gunk on the slide and outlet portion of the carb. I cleaned the emulsifier and the carb, it seems like it is beginning to st...

Even though we have a bit of nice weather ahead, I am thinking about winter maintenance for the TTR which may include the top-end. The bike is now 10 years old, runs OK but I really don't know much about it's maintenance prior to my getting it 3 years ago. Seems like a valve job, timing chain, etc. certainl...

Years ago I before 0-ring chains I used to remove the chain wash it in paraffin and cook it up in 'linklife', hang up the warm chain over the tin as most used to run back, worked well. For the last few years I've used Chainsaw oil before each trip of say 100miles, often over oiling to let the surplus +dirt ru...

Hi, If your like me and riding the bike in the high rev range you might be looking for a tacho. This is the tiny tach and I have found it very good. It is American made and is also an hour meter. Regards, Matt

Picked up a front and rear wheel to keep knobbys and a 50 tooth sprocket on them for bush rides. They are the purple rims and they will be going on a blue model.

hey! I have a 2001 ttr250. bought it from a guy for 450 bucks with the title! bad thing was it smoked and he said it would stop once it wormed up never stopped...

Since I bought my TTR a couple of years ago it's been a bit spluttery cold and less pickup against my son's TTR, I have done the normal stuff x3 times or more. Then looking through the parts list Brian mentioned about pilot jets being difficult to clean, so I ordered up a couple of replacement jets a bit lar...

Hi everyone, another problem again. After my spirited riding at the MX track last month, the bike doesn't feel the same. At about half throttle, she develops a splutter which leads me to think about fuelling issues again.

But I also noticed that the compression seems quite low, I can near e...
