(Preview)
Oops! Had a bit of an off today and have smashed the speedo and broken off the warning light assembly too (as well as knackered the cowl). Does anyone have any ideas for replacement, since I assume I won't be able to get stock replacements easily. I know I can change to an aftermarket digital speedo and p...

Oil Type - 2003 Yamaha TTR 250

Curious what oil I should be using in my bike? It’s a 2003 Yamaha TTR 250. Owners manual says 10w-30 or 20w-40 (depending on outside temperature?)

(Preview)
Morning all, Just wondering if anyone has any experience of successfully upgrading the suspension on their bikes? The front end tends to be a bit twitchy with the whole set up being very soft. I know it’s a trail bike, but the front does tend to ‘dive’. Can you buy upgraded springs in the UK? I’m around 90...

Clutch switch
(Preview)
I’ve managed to rip the wires out of the back of the clutch switch. My TTR will now only start if it’s in neutral. Logic says I should be able to join the two wires together and make it so it will start in neutral and in gear whether the clutch is pulled in or not. I’ve tried that as a temporary solution but the b...

Wiseco Piston Clearances
(Preview)
Following on my earlier post, I have removed the head, barrel and piston and determined that the existing piston is a Wiseco 4689M07350, which is 73.5 mm nominal (0.5mm over stock). While I fully recognize that it may make sense to replace the piston regardless, for diagnostic purposes I want to veri...

Engine serial number - bike model/country

Hi, just brought a spare engine from a UK breaker who'd totally forgotten where it came from. It's not got an engine number, just 4GY stamped on the boss, doesn't appear to have been messed with and no sign that the cases have been replaced unless it was a very long time ago (also unlikely at £2K+ a set!)....
