GR650 Tempter chain and sprocket questions

[Guest]

Yep..that must be him. I didn't know he was posting on Do The Ton, but I know he goes there a lot.

Yep, wood screws...and other things. But I really love fixing a "problem" bike and getting it up and running again! It's an awesome feeling.

How's the bike coming along, Super? Just got to ride mine with new sprocket today. Huge improvement. Bike pulls better in every gear and doesn't have the "running out of breath" feeling it used to exhibit.

Excellent way to spend money on a bike.

Hey oldrookie. It's coming along just fine. I ended up going one tooth up on the front sprocket and a new stock rear sprocket. Just like you. Today I plan on attaching the new sprockets and getting the new tire put on the rear on Tuesday. I also already installed new rear brake linings. So I'm getting real close now!! Basically, put everything back on the bike and crank it up!!

Real glad to hear you finally got to ride yours with the extra tooth on the front sprocket and everything rode well. That makes me feel better about changing the sprocket now that someone else can verify the results. I'm really intrigued to find out how this bike will run and ride. I'm not used to riding so small and light of a bike but if what I'm hearing is true, it should be great fun. I will keep you posted.

So close you can taste it! It really is a fun little bike (never thought I say a 650 was little.)

I used to hesitate to run it at 60-65 because it just didn't sound/feel like it was happy doing it. Had it up to 70 and it was perfectly happy to do it. Sprocket really made a difference.

That's great to hear. Yes..really close now! And it's doubly hard to take as it's supposed to hit 76 and be sunny here on Wednesday! I will update you and when it's all done, I'll post a few pics.

So...how did it go? Up and running?

All right. The new sprockets and chain are on! Unfortunately it is a non o-ring chain which I didn't clue into until after I had cut it to length. Live and learn.

15 tooth front, 34 tooth rear. Ride report coming soon, weather permitting.

Weather permitted! First ride on the new drive line. Definitely better on the highway. Nasty vibes at 110km/h are gone. Now for a gas mileage check over the next couple of weeks.

For those doing the math:

Front Rear Ratio
15 38 2.53 stock
16 38 2.38
15 34 2.27
17 38 2.24 1984 Cycle World long term test mod
