[82cutty]

Hi guys...just joined the forum . Anyway I just picked up yamaha 175 tri-moto in pretty good shape and was checking it over . The drive chain has some slack and was wondering if there is an adjusment to tighten it up . If so what do I need to do to get this done . I need to get a manual for this so i know what i'm working on lol

Thanks for any help

What year is it?

Does it have plastic guards around the rear sprocket and brake disc?

83 and yes with the plastic

I am trying to go of memory,but raise the machine off the ground and then loosen the four bolts that hold the rear end on the frame , then tighten the long threaded rod underneath the rear axle to slide the rear end back, leave about 1/2 inch slack in the chain, then tighten the four rear axle bolts back up. I hope this helps

Hey Did you buy this from a kid named Brandon out in Boston? If so this was my tri-moto that i brought back from the dead. I know the machine from top to bottom. Brandon was supposed to sell it to my friend Scott but he could not wait a day and then he sold it. Also Brandon gave you a line of crap it never had a new rings put in it. Im just glad to see you on this site.

1) Loosen the 4 14mm bolts on the axle carrier.

2) There is a chain tensioner I think 10mm tighten that up.

3) It should take the slack out of the chain.

4) Tighten the 4 14mm bolts back up.

Well I went to adjust the chain and it was allready maxed out . I took the chain off and removed a link . It's back on and worked out good . I think it's time for a new chain. Thanks for the help guys :)

Also I need to get some tires...should I stick with the big balloon tires or can i get some smaller ones . I was thinking of these

wow! your chain is really stretch out if you were able to take a link out, you should replace that chain before it breaks and slams into the engine breaking the case. Them are the same size I am going to purchase next because I am sick of my balloon tires also, just remember that the "balloons" are your suspension so if you go with smaller ones it might not be as a smooth ride and your going to lose a little top speed with smaller ones.

Yeah i'm going to get a new chain...there's a couple on e-bay . I can get those tires in the stock size also.

[old-yellow]

its up to you if you want to stick with the stock size, I think size 20x11x8 will be fine and not really affected the handling that much, that's what size I am going to get for my next set of tires.

Yep, It was mine I traded my 225dr for it along with a 125m. Ill tell you some stuff about it so you know what in needs or whatever. It is actually a tri-moto 125 but it has a 225dx front end and headlight. It was like that when I got it. Brandon had a trx90 that i wanted so i traded the tri-moto for it. He said he was going to keep it but the next day it was on Craigslist

[Derek]

lol its funny you said that because it had nice tires on it and i pulled them off right before i traded it.

I thought it was a 125 when they brought it over... oh well...it runs great . Guess i need to look for a 175 motor . What pre-mix oil did you use ? I'm going to fix it up a little . Re do the seat and paint the plastic . Some new tires too

You can bring them plastics back to there former glory by wet sanding them.

Here's a link to a good thread about wet sanding.

[Derek]

I ran 30:1 in it i kept it a little rich just in case

[TriMotoMan]

i run 40:1 in my 125 and she runs awesome and has no problems

[82cutty]

Ok thanks guys...what kind of oil do you use ? I looked all around my area for some amsoil...nobody has it . What else is good . My autozone has some valvoline syn...for like $ 6.00 a quart is that ok or should i stay away from it ?

[TriMotoMan]

i use yamalube premix race, chevron high performance snow machine, and valveoline

[old-yellow]

I use Pennzoil outdoor or if I can't get Pennzoil I will use Valvoline multipurpose, I have never had a problem with ether one.
