izzywithus Posted January 17, 2010 Report Share Posted January 17, 2010 Hi all, I have a 1997 TYZ 250 "Scottish" with the steel tank and swing arm and road kit. It is not premix but has a gear driven oil pump and what I think is a second very small oil tank and pump which is wired into the loom. The problem is that it is delivering too much oil. How do I reduce the the amount of oil it delivers? Any suggestions would be great. Cheers Iain Quote Link to comment Share on other sites More sharing options...
alan_nc Posted January 17, 2010 Report Share Posted January 17, 2010 (edited) Izzy, You shim the pump to change the amount of oil it sends. It is a trial and error effort. I think you will find that most everyone here has removed the pump and is using pre-mix. With modern synthetic oils the mix is so different from 10 years ago that the pump no longer functions properly. If you do a search there is a long post somewhere on specifically how to do the shimming. Alan Edited January 17, 2010 by Alan_nc Quote Link to comment Share on other sites More sharing options...
izzywithus Posted January 17, 2010 Author Report Share Posted January 17, 2010 Thanks for that Alan, I will do the same and remove the pump. Do you just tape up the wires and leave them in place? Cheers Iain Quote Link to comment Share on other sites More sharing options...
alan_nc Posted January 17, 2010 Report Share Posted January 17, 2010 Iain, Before you get to carried away with changing things lets see if we can get further advice from Feetup or Tony or one of the guys that does a lot of work on these bikes. There may be a reason on this particular bike that you want to keep the autolube - I really don't think so, but lets give the others time to chime in.

woody Posted January 17, 2010 Report Share Posted January 17, 2010 A TYZ with autolube, steel fuel tank and steel swingarm ?? Quote Link to comment Share on other sites More sharing options...
izzywithus Posted January 18, 2010 Author Report Share Posted January 18, 2010 Here is a link to an advert for the original bike. Before you ask I am not the rider in the top middle!!! http://www.trials.com.au/content/index.php...er&Itemid=6 The tank takes about 6l (not the 4.5 on the ad) there is also a de-compressor which I have never seen on a 2t before. The white box over the rear wheel is for the battery. The bike seems to be made up of parts from a 4GG motor and chassis etc with some 4ML parts to make life really difficult. The autolube seems over complicated as it has 2 oil tanks and 2 pumps and is connected into the loom. However, I have done 3 trials on it so far and it's great to learn on.

woody Posted January 18, 2010 Report Share Posted January 18, 2010 The link just goes to the main forum but managed to find a couple of your pictures of the bike you'd posted. I'd heard of the TYZ Scottish but never seen one. I'd no idea they were like that. Quote Link to comment Share on other sites More sharing options...
izzywithus Posted January 18, 2010 Author Report Share Posted January 18, 2010 Thanks for your comment Alan, I'll wait to hear from the others if they any thoughts. Could you give me an idea of the thread title you mentioned. I have not found it yet. Woody try this link for a picture. http://www.tomina.ro/motociclete/288-Yamah...cottish%20.html Cheers all Iain Quote Link to comment Share on other sites More sharing options...
