I'm attaching a doc written by an engineer, Mark Lawrence at Cal Sci (fellow rider too). It has everything you could possibly want to know about motor oil and how/why it works in a motorcycle engine. It is a long paper (16 pgs) but it is easy to read and explains everything. I skipped to the stuff about motorcycles first time, but I found i kept going back to find out more. Eventually, I sat down and read it start to finish... it's worth reading. In a nut shell... Mark says use Mobil1 15w-50 if you will not be riding in any cold/cool weather. If starting your bike below 40°f, 5°c use Rotella T Synthetic 5w-40. If you can afford it, use Motul 5100 10w-40 or a blend with Motul & Rotella T synthetic or another high quality synthetic. I use a blend of Rotella T syntheic 5w-40 & M1 15w-50 in my air cooled V twin and my VFR. Everything you want to know about oil.doc

Veefer800Canuck added a link to another post for ceramic wool as the muffler packing material. It's in the post for "Best Grade Of Stainless Steel Wool For Muffler Repack ?" I tried to copy and paste, but it didn't work. I'm going top try the ceramic wool as a packing for my new exhaust that should arrive tomorrow. Here's the link... http://www.anvilfire.com/sales/k_index.htm Like to hear how the finished project sounds...

BR, FM, & Veefer you guys ROCK! :fing02: Thank you so much for clearing this up for me. Hopefully, I'll have everything done by Spring. :wheel: I'd give you an official "Thank You" for your profile, but I don't know how to do that... I looked, but I'm a little slow sometimes :comp13:

Thanks BR! I knew a quick answer was out there. Now, if you don't mind, I have a couple of follow-up questions. Do I just swap the F4 tubes into my VFR or do I use the F4 steering stem and the VFR upper triple tree? I thought the F4 tubes are 43mm and the 5th gens are 41mm. Do I need to get a different triple tree? RE: spring rates, I weigh 220+ lbs buck naked so I'm looking at getting a set of Traxxion fork springs to bring the spring rate up into my weight class. What are your thoughts on the steering stem bearings? The bike only has 15k miles and while I have it apart I can replace or upgrade. Also, if I pick-up an F4 rear shock do you think the shorter fork tubes and shorter shock would keep the steering geometry about the same? Thanks for your help...

Hey folks, I've got a question and hoping for some input. I know there are a TON of posts regarding fork swaps and upgrades... I've searched and read many of them, and quite frankly, I'm swamped with info and I'm hoping for some clarity. I would like to upgrade my suspension in the near future and also de-link the brakes. I promised myself when I bought this bike I would leave it alone, but I can't help myself and I want to tweak & mod. Suspension seems to be the biggest area we can improve these bikes. Mine is a bone stock 2000 VFR and I would like to know if I can swap a F4 fork (1999) onto my bike? I will have the complete fork tube assemblies, steering stem, calipers, & M/C to make the swap and do the de-link of the brakes. Can I do this swap and is it worth the effort? Can I get better results with a different mod? This is my 1st Honda motorcycle and I value all your collective knowledge. Any help, suggestions, or insight is greatly appreciated. Thanks...
