gazzaecowarrior Posted March 18, 2009 Report Share Posted March 18, 2009 Hi there Just bught an old TY175 to restore and am picking it up on sunday. The autolube has been taken out and I was just wondering what sort of pre-mix ratios people use. I run my Beta on a 70-1 semi synthetic mix so would the same be suitable ? Also does anybody know if the TY175 has the dreaded Z spoke system. As I haven't seen the bike I can't tell and the guy I'm buying it off doesnt care what spokes it's got. The only reason I ask is because I had a TY250 mono which needed a wheel rebuilt and all the wheel re-builders near me refused to touch it because of the Z spokes. Finally, does anybody know how the frame and engine numbers correlate to the year of prduction so I can work out how old the bike is ? Looking forward to some good responses off you twinshock boys !!

paul w Posted March 18, 2009 Report Share Posted March 18, 2009 i rum my ty 175 on castrol tts at 50:1 with no problems, but some people say even this is too lean? as for dating, write to the customer service deptment at Yamaha uk with the frame and engine numbers, they should send you back a dating letter, good enough to get the bike road registered if you want. my bike has got conventional spokes. post some before and after pics so we can have a look. cheers paul.

majesty320 Posted March 18, 2009 Report Share Posted March 18, 2009 Use a decent semi synthetic oil 50:1 is no problem and wont gum everything up, ive just had two sets of wheels rebuilt with no problems one in stainless and one standard. if you need to know any thing ty related speak to this guy http://www.tytrials.co.uk/.
