I'm hoping I can gather enough information to finally get my bike running after five years in the garage. I'll start at the top but if you don't want the whole story, just skip the next two paragraphs...
In 10/2001 I installed a Mr Turbo unit on my '99 Busa, took it out for a successful test ride, then put it away for the winter. In 05/2002 I had a medical problem that kept me off the bike for years, except for one short ride each summer of 2003-2005. During the ride in 2004 I noticed smoke coming out the exhaust but didn't think anything of it since the bike had sat so long. In the latter part of 2005 I decided to ride regularly but was plagued with what I thought was white smoke, pouring out the exhaust. This past winter I pulled the motor to replace what I thought was a leaking head gasket only to find the scavenger pump was the problem.
After some research, I feel I know enough to refer to the scavenger pump that came with Mr Turbo's kit as a tiny piece of s-h-i-t. I called Mr Turbo a couple weeks ago, and basically ended up with his heavy duty scavenger pump ($250). Well the (unused) pump is going back tomorrow after finding out it is a GP-301 from Reverso Pumps which has a max operating temp of 140 degrees, well below the operating temp of oil. Reverso says the pump will withstand short periods of excess oil temps (i.e. drag racing) but will not hold up to sustained periods of riding (i.e. trips). Add to that the fact I was charged double what the pump sells for and I'm finished with him.
When I found out how large a true scavenger pump was, I couldn't find a reasonable place to mount it on my Busa, which is why I started a prior topic asking for help with a mounting location. Although there were no suggestions, I was introduced to the NLR mechanical pump which replaces the starter cover. So here is where I stand...
The Mr Turbo pump runs for 10 seconds when you first turn on the key, probably to pump out any excess oil that accumulated in the turbo cavity since the last shut down. Any electric pump can have that option as well as a delayed shut down which would let it run XX seconds after the motor is turned off. Both of these together seem to be pretty important from what I've read and I feel using an electric pump designed for this purpose would hold up for a long time. The disadvantages to such a pump are it's size and mounting location.
The NLR mechanical pump can only operate when the engine runs. Since the starter cover is higher than the outlet on my turbo I'm assuming any oil in the line will backflow to the turbo. I know there is a check valve in the line running to the turbo, so maybe there needs to be a check valve in the line running back to the mechanical pump. It doesn't look like one is furnished with the NLR unit so I'm wondering if my reasoning is flawed, or what. If I should use a check valve, then I have no clue what to get or where. I'd also like to find someone else that has used the NLR unit and I'm interested if anyone else makes something similar just so I can compare them.
I'm not putting down the NLR unit by any means so please don't think I am. I'm only trying to do the right thing without losing more money or what's left of the riding season. Had I asked questions before purchasing Mr Turbo's kit, I would have never made the purchase. Hopefully enough people will pitch in and we can see where this goes. No matter what, thanks for reading.
