belt to chain conversion for a savage 4 speed
04/08/10 at 16:21:08

got a question for you guys I recently busted my belt and i was reading the technical section for this mod and was pretty impressed by the results More speed, better MPG depending on gear ratio, unfortunately there was no info on this mod for an older savage 4 speed only 5 speeds any opinions has anybody done a chain conversion for a 4 speed theres a bunch of gear ratios and percentage info i really didn't understand very well, so if anybody could shed some light on this i would really appreciate it.

thanks guys youve always helped me out with my love affair with the savage.

So, if you're not to heavy,.. to handle a higher 1st,.. the taller 4th gear might be very nice...

Was that with both of them in 4th gear; or the 5 speed in 5th, and the 4 speed in 4th, in other words, both in "high" gear? That might explain the difference in agreement? Undecided

Re: belt to chain conversion for a savage 4 speed Reply #9 - 04/09/10 at 10:24:18 IIRC, a 4 speed in high gear @ 60 MPH is turning slightly fewer RPM than a 5 Speed in high gear @ 60. Remember, they changed the jetting somewhere "back there", IDK if it was when they went to the 5 spdeed, but that would at least offer some reason for the gearing change.

KLX in top gear does 63mph @ peak torque on std gearing (15/43), I went to 16/42 and she now does 69@peak torque, very nice. So I am going to try 16/39 which will give 74mph@peak torque and 104mph@peak power.
The good thing with chain drive is the variety of sprockets available to do with whatever you want.

I did 16/41 which is about 17/43. It was okay. Much more comfortable at highway speeds but Ive got a ton of hills in my area (Penn Hills PA) and I did miss the bit of low end grunt that I traded. I was however, able get very very close to or a bit past 100mph on the highway when the speedo reading was adjusted for the change. Took a while to get there though. If you dont live in a very hilly area 17/43 would be a good choice. If you've got hills Id go 17/45-47. and I would NOT use a 16 front sprocket. 16/41 the chain was very very close to the swingarm and on large bumps would scrape. Required very close attention to chain tension. 16/43 didnt scrape but was still close. I just think 17 is the better choice.

The bike to look for as far as the sprockets goes is suzuki gs550 (with cast wheels, not spoked) '83-'86.
