issue with drive line on 97 B6
« on: June 20, 2012, 11:26:39 AM »
hello i am in need of a bit of help... on my bandit when i am cruising at speed (highway 55-85) and i give it gas there is a lag, then sharp pull... it worried me so this is what i have done:
- my chain was shot so i replaced that
- checked the front sprocket to ensure it was tight, it was not so i tightened it back up
- new chain is lubed and adjusted
- front sprocket still has allot of life it in as does the rear

Now the bike when i am riding and come off the gas will hear a clicking sound from the front sprocket (reason i thought it was loose) and i still get the lag and pull when accelerating at highway speed.  Any help would be great this is my daily rider and i need to keep it tip top.. i know allot of people will suggest the carrier bearing but i replaced all the bearings when i powder coated the rims last fall, any advice on where to start would be great

- chain 530 o-ring 110 link
- front sprocket T14
- rear sprocket stock
- year 1997
- 600 cc (stock pipe single baffle removed)
- plugs and wires replaced 8 months ago
- all service reg scheduled is performed on time

I also think i may just go ahead and replace my sprockets front and rear... would a 14/48 set up work on a 110 chain?

The "lag and pull" part sounds like carb tuning issues rather than the chain.  The clicking noise could be a chain that's out of alignment - never trust the marks on the swing arm to verify rear sprocket to front sprocket alignment.

There are several commercial units you can use to check chain alignment.  I opted to make one out of wood with a brass rod (arrow shaft works well too).  Basically, you need to have a flat surface on the rear sprocket that the rod/shaft mounts to.  If the tip of the rod extends to the front and is still in line with the chain you're good to go - regardless of the marks on the swing arm.  One or two changes of the "flats" on the adjuster nuts will make a huge difference.  Here's a pic of my rig for an idea.

I use a tape measure, and measure from the centre of the swingarm to the centre of the rear axle. This won't technically align the chain, but it will make sure the rear wheel in aligned in the swingarm and frame. Easy to do.

Sure enough the adjusters in the arm are off... I measured from my spools knowing those are even on each side and the axel is off I am going to make a measure tool like a Harley would use to get this sucker even. Thanks! Y'all saved me from buyin $75 worth of sprockets for no reason!!
