Started on a bikini fairing today, looking at a few different angles. Let me know which angle you think looks best.



A full profile photo of the bike might be needed to give a better idea.

The first pic lines up the lip of the fairing with the outside line of the headlight, looks better that way... ;)

Thx Retro, I agree with the lines around the lamp, even perhaps slightly forward so it sits just behind the trim. I've got enough length in it that it would have those lines regardless of the angle, I'll trim to suit. So I'm thinking the lamp lines of the top one, with the angle of the bottom one.

Thx SF, this bike won't be much of a cruiser. With the clip ons and rearsets, I'll more than likely be laying on the tank from time to time. Aerodynamic, I think. Once it's on the road, I'll have a go at making some different pipe set ups, that will let me fit a bottom cowling.

Damage, i like the angle of the top pic as well, sit on the bike and see where the air it deflects will go, pic 3 looks like it will hit you square in the face.... You'll hate it if it does, it will buffet your helmet and drive you mad... ;)

Thx Trad, as it turns out, I've had to increase the angle slightly and I've moved it forward as well. This is were it will stay.

G'day all.
I'm after some advice please.
Originally I planned just a top end rebuild, so I purchased a gasket kit to do just that. Now I've decided to strip the bottom end as well.
My question is can I get a bottom end kit or do I need to get the rest seperatly? If so what do I need to get? Should I get a complete one and off load the top end one? I got this one off eBay, is there some where better to get them?
Any advise would be appreciated?

What's prompting the bottom end rebuild?  There is no turn-key bottom end kit.  The most important thing about the bottom end is checking wear on the crank, rods, bearings, transmission, primary chain and primary chain tensioner.  If you are going to rebuild the bottom, buy a new primary chain, too.  If you are looking for mods, one is to have the crankshaft balanced.

When I purchased the bike, the top end was removed and I don't know for how long the case was open to the elements. Anything that could've dropped in past the pistons could be still there. So it's manly exploratory, and I can check wear and tear while I'm there. So as far as gasket options, a complete kit or separate individuals, looks like my options. I'll look into that crank balance, might be able to squeeze more coin into it. Thx

I picked my head with new valves and seals, valve seats and ports done as well.
pick up piston clips early next week, then I'll have all my bits to put it back together.
That leaves me with the carby rebuild. Need to save some bucks to get 4x rebuild kits, in the mean time I start stripping them down.


It looks like you had a nice clean bead blast of the head and replaced the valves and seals.  Springs and retainers, too?  Who did the port job?  Can you take pictures of the intake ports.  Mike Rieck is the resident porting god out of Massachusetts, but additional resources are always good to know especially if it is local for others.

When I've said "ports done", I don't think it's a complete port job. My local ( Geelong, Victoria, Australia) motor reconditioner, who builds mainly race car engines. When I got him to check the head, he recommended new valves. The springs and retainers were fine, so they weren't replaced. When he did the valve seats, he machined into the ports about 15mm, if my memory serves me correctly. Tried to take some photos, but too dark. I went and spoke to one of the guys yesterday, about the crank. They don't have a lot of experience with bikes and this bloke felt that the crank would probably be close to "spot on", due to its Japanese construction. I say this not to question your suggestion of a crank balance (I think it's worth looking at), but to highlight the mind set of the machine shop guy. He said he will check it out for me.

Cycle X typically finds the crank and rotor to be slightly out of balance.

Just a couple of question on some mods that I'm considering!!
Firstly, with the clip on bars. I'm going to have an issue with contact of the hand controls onto the tank. Two remedies I've considered are tank dents and a turn reduction by altering the stops.
Initially the tank mod was the way I was thinking, along with knee dents. But I have grown attached to the original shape of the tank and not to keen on the thought of the reduced fuel capacity.
So I've been considering altering the stops. I can see that it will affect parking, but as I have limited road bike experience, I'm wondering how much it will effect general travel or emergency manoeuvres.
Secondly, on a performance level. I've had a bit of trouble finding the rest of an airbox over here in Oz. So I have the chamber that the carbs attach to, but I don't have the filter box. I have seen a adapter plate made that attaches to the chamber of a single larger K&N filter or other brand. The question is has anyone had some experience with this type of set up and what did you discover?
Any feed back will be much appreciated.

 If you want clip-ons and to retain the stock tank, get some that have a rise to them and are adjustable in the "pull back". It should allow you to have the best of all worlds.

Thx calj737, unfortunately I already have some clip-ons and they aren't of the adjustable variety. I suppose I could consider resale and update to a adjustable set. That's an option.
