BEC mid engine
Evening all. Im a noob
Ive got a few questions i hope you can help me with?
Ive brought a mid engined BEC that was a non runner. Its got a GSXR1100 engine. Its got a hydraulic clutch and a push/pull rod to change gear. Does
anyone know how hard it should be to select gears? From N to 1 took me a few mins to find and from 1 to N the same.
Its track only with no reverse so ive only driven up and down near my garage...10 metres max
As soon as i figure out how to upload pics i will get a few of the car
Cheers

Finding neutral can be a pig sometimes, should drop into 1st though without any difficulties, 1st to 2nd is the clunkiest gear change, the faster you
go the easier/slicker the gear change is though.
Make sure you have a stop on the clutch pedalnif it docent have one fit one, your left foot is a lot stronger than two fingers, it's possible to
operate the clutch to far and cause damage.
Welcome btw.

If the oil is fresh and the clutch isn't sticking (i.e. engine has been run recently), you should be able to change the gears easily.
If engine stopped then you should be able change down to neutral, although finding neutral can be tricky sometimes (depending on the state of your
gearchange mechanism).
Gearchanges are better still if things are moving and I do have the odd problem with finding neutral if I let the car stop (with the engine running)
and the oil level is low or contaminated with fuel. I have always assumed this is clutch drag.

Wow, quick replies
You both may have hit the nail on the head. The cars been stood for 3-4 years. The oil is probably knackered. Ill get some new oil in it tomorrow.
And again, i was using the clutch like a car, pushing it right down. Ive got a zx10r race bike and use 2 fingers for the clutch so that was a very
good point
I need to find a private closed road to test it on and see if its as it should be
Is there a way to add pics on here?

My first two GSXR1100 engines were very difficult to find neutral in. The current one (rebuilt at the beginning of the season) has no trouble. So the
answer is (I guess) that they shouldn't be difficult but it often can be. As Matt says, oil condition/level does seem to have some effect!

It started life as a hill climb car with a car engine..
Then the guy i brought it off...conceptracing.co.uk stripped it, made it a single seater, hand made the body work and turned it into a BEC

Out of interest, is the gsxr1100 a watercooled or air/oil cooled model?

It's water cooled. I think it's a W model.

The watercooled (WP onwards) engines are incredibly good, very strong and VERY tuneable. Your pocket will be the limiting factor, but the engines can
take a huge amount of abuse, from excessive boring to forced induction. Play.
As for neutral, it only takes the slightest loss of the points on the drum (normal wear) and gears become less selectable. I suspect, however, that as
you get used to the powerplant it'll all seem very much better than it may do at the moment.
I guess you could always fit a Pinto if it all seems too much :-)

hahaha...the good old pinto!
Its got a hand made forced induction, sort of ram air. I will get a pic up tomorrow.
I think the main issues for me is getting it somehwhere to give it a shakedown. Im looking at getting it on a dyno to iron out any issues but first
need to get a tow bar/electrics etc
Im 6'1 and couldnt fit in it with the old seat. The guy i got it off was about 5'5 so I need to get another race seat thats wider, and
with a more upright position.

That makes 3 gsxr1100wp on here (well Cloudy has moved on to R1, but I think he regrets it).

What sort of power will a standard lump kick out?
