what is the deal...
What is the deal with this Pair Valve I keep hearing about?
I'm beginning to wonder if I may be a victim of this device. The bike ran GREAT when I first bought it. AFTER the first maintenance, at the Suzuki dealership mind you, the darn bike sputters a bit in first gear when I first start off... like it isn't warmed up. This, even after I let her run with choke for 5+ minutes, and choke Still on.... Is it the darn pair valve deal... or something else.
Definitely need the advice of a real wrench turner on this one, as the service dept at the dealership obviously screwed something up. Not even sure I want to take it back to them, there is Always a wait to have them do even the simplest job!
I went ahead an ordered the tech manual for the VL800... pink cover and all. Is this something I can do? Not being the most mechanically inclined, and all. Thanks in advance!
C-ya,

C-ya,
No the pink book is definitely not friendly to less experienced mechanics. It will not help you troubleshoot the problem and many of the simpler procedures are left out. I guess they assume that everyone has 20 years experience fixing Volusias. I've worked on my own cars and trucks for over 35 years. I've done everything from brakes to engine and tranny swaps but I found the pink book useless. I have no desire to buy the special tools and learn the procedures in that book. If I need an engine or tranny rebuild I will leave it at the shop. I'll do brakes, tune-ups, clutch and shifter adjustments and that kind of thing but I found that info to be skimpy at best. I'm waiting for the Clymers.
As far as your problem goes, it sounds like you might be running lean and yes this can be caused by a defective pair valve. Moccs place has a procedure for bypassing the pair valve. Try it and see if it works. It's simple and easily reversible. His instructions are also better than the pink book.

If your pairvalve is disabled, then YES pipes leaking at the heads could cause backfire.
It appears the majority of the backfire issues related to pipes deals with the Hardkrome 3 inch straights. It seems to be a gasket issue that resolves this problem.
When I installed my kickers, I looked at the gaskets, they seemed fine and I continued installation. A lot of guys with 3" straights do this, yet after installation find they should have replaced the gaskets.
I am starting to think we should let anyone who is buying them, know that they should spend the extra few bucks and replace gaskets when buying the 3" straights just as a precaution.
The 3" straights must be very particular. The angle that they come in to the heads must be so specific that it becomes a real demand for an absolutely perfect (aka new) gasket. Obviously its pretty darn hard to get any kind of torque wrench in there, but tighten those bolts down good nonetheless (definitely dont kill 'em though). I found it really helped to use ball-ended allen wrenches which let me get into the bolt a lot better.
Good luck, maybe someone here has the part number for the gasket?
