Offsetting is this to upset the harmonics in the bar sort of thing Blue.

I well realize that there are so many variables here that what works for me is truly and individual solution.

However, the discussion did bring out some "tips" at least one of which I've not heard of before. (decentering)

Yes, I did think of the crossbrace. Mine has the ability to be unbolted at a clamp-type fixture. Tried it both ways with no real perceived affect.

"Decentering" I have NOT yet tried but will give it a go a report back....good idea, that.

Do Pumper Carbs smooth out the engine? Changing from the CV carb to the FCR carb on my DRZ400 did make the engine smoother. Can I expect the same on the Big?

I'm still playing with an easily modded foam filter for the bike using the standard airbox. I know that a complete rebuild is the best way but I'm trying to find something that a normal guy with just a few tools can do to improve the bike.

On the whole.....I like the 750 engine best.

If you don't want to speculate about lean/rich issues, I certainly wouldn't recommend the use of an O2 sensor.

106mm pistons

Guys,

I received the pistons today! Thanks to Ray (Ladder106) who helped me out with shipping.

For those who do not know - 2nd oversize pistons (for 106mm bore) are not available any more from Suzuki. So I ordered a custom made set of 4 forged pistons from Ross Racing in California. They turned out beautiful. I had to buy 4 because it was their minimum order.
Ray has taken one for his 750. I will keep 2 for myself, so one piston is up for sale. Ross made piston + pin set is 84 grams lighter compared to the Suzuki's 1st oversize piston set.

Some features:
Forced oiling on pins (oil scraped from cylinder wall by oil rings is forced to pin through special channels).
Lubricative skirt coating.
Top Seal rings.
Spirolox pin retaining rings instead of wire.

Anyone interested please PM me for price and shipping cost. The price will be lower than Suzuki original parts cost but not much.

I will cross post it on drbig.info forum, too.

That's what the package stated. Haven't read all the instructions that came with them however.

Don't really know what "gapless" means. Never dealt with that before.

Opinions?

Piston rings

No, they are not gapless. I asked them to supply conventional rings. I think they've included gapless rings instruction sheet as an advertising material only.

There is some info on TotalSeal webpage, including gapless rings:
