How long does the sprag clutch last before it goes bang and takes engine with it, my ttr has 6,300 miles roughly If i buy a kick start kit and undid the connections for the starter would that prolong the life of it. how reliably is a ttr for everyday use and whats typical mpg

Having just gotten my TTR, I am going through repairing the odds & ends that are damaged or broken, one of which was the headlight/plate. It had a broken tab on one side, presumably from a spill & was bouncing around pretty good when I got it. Instead of repairing the one tab, I decided to remove t...

To try and take the guesswork out of which size cable clips go where on the frame, I decided to be more methodical on the last dismantlement of a metal-tanked OE. Raids and blue TTRs might be slightly different - but I don't think they are! I took off 11 clips and they are four different sizes: four 6mm, one...

Hi All Some help needed please... Has anyone got a rear shock not fitted to their bikes, needs to be from an OE or Blue bike, not a Raid (i have one of them here) I need the measurements eye to eye, please. The Raid one measures 444mm eye to eye, is the OE or Bluey the same? I don't want to take the one off my bike f...

In a winter time while my bike was sleeping I decided to fix a rear shock. Sometimes fixing can make things worse. But this time I succeeded. The shock was leaking the oil a little bit. I didn't want to repair a bike in summer during offroad season nor buy OEM shock or aftermarket cause they are to expensiv...

I'm a RAID owner with a standard rear shock unit that looked as though it had never been touched. Given that my bike is a 1994 model, time for a strip down, clean and oil change etc. I acquired an old standard rear enduro shock unit from ebay and decided to strip both units down simultaneously, so that an...

I had are request from Joel in Australia for some ideas to sort out his after-market starter motor. When he pulled the body off his starter's armature, the magnets had come adrift of the body (unglued) and hence got caught up in the starter armature itself. This had been a bit of a problem for him over the...

With the current interest in big bore kits that require the crankcases to be stripped for boring to take oversize sleeves I thought this would be a good time to create a pictorial guide to include a full strip down and rebuild. I am hopeful that the 350cc big bore kit will prove successful and, if it is, th...

Hi all, My 93 OE has had several regulator/rectifier failures over time. I have a kickstart as well so I continued using the bike while waiting for parts. Each time I've ignored this, the stator has failed and needed replacing or rewinding. When I got the bike the wiring loom had been thoroughly butc...

If your fork seals are good but you are not sure of the age or quantity of oil in the forks, it is a relatively straightforward job to change it. First up after removing the forks from your TTR is to remove the gaiters and check that the dust seals are not oily coz, if they are, then you should probably be cons...

The speedo drive on the TTR can easily be stripped out and rebuilt.The photo below shows the parts involved and I am pretty sure the drive can't be dismantled further.

So it doesn't matter about spacing the rings after all.
