DT125R FORUM

@dtluke Yeah nice man.

No probs, happy to help 😬

@AndyYam and yes, I really want a zeeltronic setup but they are quite pricey new and you don't see them second hand. Eventually I will

@dtluke To obtain part numbers and diagrams these 2 webby's are super useful;

Just pick your bikes year etc - HTH 😉

Will a 1989 3MB head fit the 3MB barrel of my 2000 dt?

Thanks again. Will plug it up

Best give him a ring really. Doubt he really checks his Facebook. He is a nice enough bloke you can ask him.

When I spoke to him he quoted 170 for barrel ported and head squishband and powervalve adjustments.

In order for him.to.do his work he needs the piston you are going to use, barrel and of course the head.

@irongamer727 well, tap water has minerals in it which will be deposited inside the coolant jackets as time goes. This can affect the cooling. Also iron parts may catch rust as well. You may have to flush your cooling system more frequently compared to using distilled water.

DOH! didn't look at the back of the haynes manual (pg140) where they added later bike models. From 2004 onwards the main jet was 210 and pilot was 17.5 - so my bike was set up correctly! Problem now is my jet needle is a little bent and shows excessive wear on the bent side which means I need to replace my needle and needle jet ( 5j40 and q2m(939) ) but I can't find those anywhere on the web.

Yeah which is why it was a side note rather than a big point. Still not something I would do personally.

@yammad will do, 2005

@Calum there are not that many suitable wheels on eBay and definitely not any cheap ones. Might look at this route then. Cheers again

@Calum thanks, ordered one

@MIGHTYMAN cheers, yes I got it too small. I took the barrel and piston to some one near me today who sells the pistons on eBay. He immediately sorted me out with the right piston which was a .50 oversized and a new gasket set. The one thing I need now is the little orange gasket in the power valve set up. It came with the o-rings but not that gasket and mine is ruined.

@irongamer727 Couldn't find it. I did look sorry. It might be on here. Try searching.
