TURBO SV650

For kit information and our other Turbo application services please visit this link. The bike is currently being taken apart and a will be utilizing a same model bike with lower miles. I will be adding the ARP bolts and adding the stator where I cut down material to reduce over 2lbs of weight. This helps take some of the rotational mass off the end of the crank which is sometimes an issue when adding more power to these bikes. Again, with this one shown on the left, I left it in absolute stock configuration pushing often 8psig to have had no problems what so ever to over 12,000 miles.
Update 10-25-2013: Well the Turbo SV is no more for awhile. I plowed it into a 21year old girl who crossed four lanes of traffic to make an illegal left turn. Total front end damage, the front wheel broke in three places and jammed what was left of the wheel up into the front cylinder. I have four fractures in my pelvis with some shoulder damage and broken finger was all. It could have been way worse particularly if I didn't have a helmet on. It saved my face for sure and possibly my life my head went through the girls driver door glass. I had adhesion's on my face but worse sever bruising in the crotch from hitting the tank. The almost worse were the man parts got hurt to say the least. However, hoping to buy another of the same year and re-install the system on that one. I had some other goodies to add on anyway with one more fail safe I wanted to apply.
Update 7-27-2013:  So I now have over 11k miles on the build and it has been working very well. Not much to say on that other than I finished two more videos that I have posted below.
Yea, a little crazy I know. Especially if you know SV650's.  No one in America, that I can find, has built one. A handful of SV1000's and a few TLS's but no 650,s. Mainly the reason, "why not" is due to the Crank being a bit weak with more pressure.UPDATE 2-7-13:  I've put about 200 miles on it and have been fine tuning for the past few weeks. Oil to the turbo is now from the engine using the electric pump to push back to crank case. Will be installing lighter stator and anti-detonate tank here soon.
 On this project I decided to take an engineering approach to this by doing some homework about the history, materials and look at overall rotational weight. So I'm getting rid of some of the rotating mass by replacing the Stator all together with thermal electrics and a design of my own on the stator itself much lighter. Also I'm limiting boost to 7psig for now. It takes just about 3psig (at the gauge) to make up for altitude bringing it closer to Sea Level 14.7 performance.

So far, at this writing, I need to paint more pieces and mostly finish electrical connections. All the fuel lines and plumbing are in. This being my personal bike, I need it to be reliable. So I'm trying to think of all the things that need to be perfect to be so. The oiling system for the turbo is on it's own independent circuit. This helping to keep out debris, primarily clutch particulates, out of the center housing bearing. I have since driven it and changing out some things on the turbo. Had to repair it due to a pump switch failier, big bummer.




GB 350 Cafe Racer

This cool little guy came to me needing some work done to make things fit and change a few things. It needed the tank to be mounted, seat with a plate so it wont crack the fiberglass, change brake pedal, foot pegs, install stabilizer, make a license plate holder and add a tail light to it. A few other little things as well. The owner races these things like crazy. The tires are shredded on this thing!  So the picture on the right is a before shot.The owner messages these engines to get into the upper 40's in HP, obviously the HP to weight ratio is a big advantage. The harder mode was to change the rear hoop to fit lower and more linear. Once the seat upholstery is on it will help fill the gap nicely. It has a great profile. From here the owner will finish her up with more paint and tlc. I'll post a final when he sends a final pix. Looking forward to it's finished look!



I had forgotten about the project before this which was another 1977 Ducati 900ss.  So I'm including some of the shots of it here as well. This Ducati will go to Auction in January in Las Vegas. The owners of both the above Cafe and the Ducati about got my arm twisted to go to the Auction. It should be quite interesting!
