Topic: upcoming project for the month when it's too cold to ride here.

[fuzzybutt]

well, i'm finally going to go big bore. i'm going to do the cycle-x 850 kit, a cam, and one of MRiek's stage 1 heads. the bottom end of the motor appears to be ok (though i will split the cases and check clearances and do a new primary chain and tensioner) i will be running stock carbs and an airbox with a k+n filter and i'm seriously thinking about a drgas x pipe as well. i am selling my 1948, pre serial number gibson l-50 to a good friend who will use this guitar and give it a good home. for the past 12 years it has sat in a climate controlled case doing nothing and i decided to do right by sending it to a good home, using the proceeds on the k4.that said, any suggestions or additions you might make to the combo? i'd love to go super big on the head but the money wont be there for that, just a goo, multi angle valve job and a cleanup of the ports and chambers. kehin cr's are also out of the question too as the money wont be there for those.

Fuzzy,

You need to get over here and ride the K4. It may change what you build. I'm not 2 hours away from you and have lots of spare parts. Drop me a PM -

Regards,
Gordon

Gordon,
Whats the oil cooler set up

[RRRToolSolutions]

Gamma, that's the old one. The one in the photo is actually an automobile transmission cooler that I fitted to the bike. I could never stop the leaks at the hose/barb fitting - even with expensive stainless covered Jeg's high-pressure hose, so I recently bought an OEM CB650 Nighthawk oil cooler (1983 model) and had custom flex lines made by Cline's Hydraulics. They do the thread-on fittings and woven braid covered pressure hoses for anything you can walk in with. No more leaks and it's all heavy-duty stuff - their ends are all factory-look solid crimped flanges too. They do tons of work for BMW, Bobcat, John Deere, and others in the area - all the while it's fine for people to walk in to the counter and ask for 2 pieces of custom hoses made with specific metric threads on one end and SAE on the other - all for $26 while I waited - amazing. I just haven't taken any photos of the new set-up, but no leaks. The hoses and threaded brass fittings were $26 total as mentioned. The cooler, stock lines, and the stock adapter were less than $50 on eBay. I haven't used the adapter (sandwich I think it's called), but may in the future. I've given some thoughts to polishing the sandwich and the stock filter cover - just for some bling. I know polished metal doesn't exchange heat as well, but I've got that new cooler up there!

I'm using Terry's machined adapter and K&N chrome spin-on oil filters.

Thanks for that Gordon, I shall now read all the previous posts on coolers, which I havent done yet.(still polishing my forks and top yolk)  But I like the CB650 idea. 
Good luck fuzzy, keep us informed with your progress, and what you decide to do.

my main reason for not going all out for pump gas power produstion is, during the warm months this bike is my main transportation. unless i''m going shopping for anything more than a 6 pack, taking one of the critters to the vet, or thye wife and i are going out together then i use the honda. i want something that will be pleasant to ride daily but still have more than stock hp. if i could find an affordable 810 or 811 kit i'd go that route instead but those are few and far bwteeen and not cheap when i have found them. i also want to be abke to still run the stock airbox as i've decided i've battled with pods for the last time. this will be my ride up to new england next spring for my youngest nieces wedding, and my ride to tampa for my best friends wedding next fall. the other idea i have is to use prepared sohc f2 rods as done my MRieck rather than spending 1500 or so for falicons or carillos. that said, thanks for the offer to let me ride your k4 gordon, i'll be taking you up on that before too long. youre right out I-26 past orangeburg arent you?

Just left of Greenville.

Gamma - here are the oil cooler pics. I pushed the bike out in the sun this afternoon to take the photos. She is dead for now, so I've been riding some of the other neglected bikes out there. Dynatek has my Dyna 2000 controler and my coils. They are great folks and even though it's been over a year - they offered to check everything out and replace if needed. Some how I've got one of the few coils that go bad - they replaced it immediately UPS 2 service.

The clearance is more than it looks - take a look at the bottom photo and you'll see there is more than 1" between the headers and the metal lines. The bike frame is powder coat, but I did not want to put a durable layer of plastic powder on the oil cooler. I shot it with Eastwood's Epoxy black which has proven to be very durable when allowed to cure. there is a slight color difference under lights, but daytime is fine. These are the stock CB650 Nighthawk oil lines - I had Clines remove the stock crimped clamps and put their high-pressure hoses on for me.

Regards, Gordon

Nice pics Gordon, that's what I will need to do.  Everything here in Saudi takes just a little bit longer, but I have now ordered the CR29's from Dynoman.
