Was going to use motul 7100 10w40

Hello all. I’ve been told it’s better to run fully synthetic oil in a bandit b12 to prolong the life of the turbo. The turbo is a gbc-22 journal bearing. Been told the clutch would slip and if it does just put some extra weight on the lock up. I assume to still use 10w40. Tell me your thoughts or your own personal set ups for oil and oil feed for journal bearing turbos. Tia Alex.

Thanks people. I’m returning the rings. Gonna get the proper gen1 rings from Nick at Sps.

Hello all. Just been sent gen2 piston rings but was told they are for gen 1. I can see on the gen2 the top ring has a rebate in it, the second ring and oil scraper look the same. Will gen2 rings work on gen1 piston or should I just return them. Thanks Alex.

Hello all. I have a bandit turbo , it’s a 1216 with hayabusa pistons in. The engine is apart at the moment waiting for rebuild. My question is, what is the standard compression ratio for a mk1 hayabusa? My reason for asking is at the moment genuine Suzuki busa pistons are more expensive than e.g Wisco or je . From my understanding busa pistons drop the compression down to 8.5-1 ? This is not a race bike it’s just for the road, so looking for around 220-240 bhp only. What pistons are you guys using and where to get them? Thanks alex

Hello all. I’m running 1216 cc engine with a Garette gbc22 turbo and I would like to know what options there are for external wastegates and what size for this application. Will be running 15psi max. Completely Standard head and timing so nothing special. I’ve experienced boost creep at higher revs so I thought I’d ask the question. Cheers.

Hello all. Came across this this evening. Ape studs are a lot thicker than standard and in turn cut down the space around the stud which must mean it’s cutting down the oil flow as well? Thoughts and remedies please. Maybe external oil lines?

Thanks for your thoughts. So I gather the cam link set up taking the port under the timing cover just gives that “belt and braces” flow of oil to the cam journals. Putting an inline rad on the “splash side” helps with head cooling.

So there is high pressure and low pressure oil in the head.? Guessing high pressure is for the cams?

Hello all. I’ve seen a few different ways of doing cam to cam oil feed set ups over the years. I’ve never done it to my bike (mk1 1200) and never had any trouble with it. Now I’m on a current build of a 1200 motor, it’s 1216cc 11-1 pistons / big valves / ape springs / Kent reground cams / ported , but is it really worth doing the cam links? Thanks in advance alex.

I’m port matching it and I already have Kent reground cams degreed in.

Hello all. Going to big bore to 1216cc. Is it worth putting big valves 26 ex 30 in I think while everything is apart? Taking head to machine shop anyway. Putting 38 mikuni flatslides on. 12-1 compression. Road bike. Would just like to know pros and cons please before I go down that route. Thanks Alex.

A well know turbo conversion company has put a spacer plate in but hasn’t altered the cam timing to compensate. Will it make much difference to performance?

Hello all. Dose a base plate spacer alter the cam timing? Eg when you put busa rods in. Thanks Alex.

Hello all. Have got myself a dyna 2000 for my b12 mk1. Full advance timing in the instructions say 35-40 deg has any one set there’s different for better results? I have 1mm skimmed head /Kent reground cams / bit of porting/ 1216 big bore/ 38 mm flatslides. Any good advice will be much appreciated. Alex.

These.

Hello all. Could someone please tell me rebore tolerance on a 1216 big bore . Thanks Alex.

Hi all. As of this morning I think I’ve done the bottom end on my b12 mk1. Don’t know what damage has been done assuming a full rebuild. So while I’m at it what’s best 1216 or 1276? If you could tell me your builds ie power/ reliability/ pros/ cons your help will be much appreciated thanks alex

Hello all. Can you tell me the piston to bore tolerance when fitting standard hayabusa pistons to a b12 barrel for turboing. Thanks in advance.

Hello all. Are there any oil cooler upgrades available? I’ve seen earls do a extra wide cooler. Is there any advantage on using an-10 over an-8 fittings or am I just wasting time looking in to this. I have two mk1 bandits one tuned and one turbocharged both get hot sitting in traffic or flat out for to long. I am currently running aftermarket 19 row oil coolers on an-8. Thanks in advance alex.

These are the calipers I have. I believe they are k1 1000 each caliper has 4 large and 2 small pistons. I am running 19x20 magura radial and braided lines.

Hello all. I have a mk1 b12 it has a gsxr750 k1 front end and gsxr1000 k1 calipers someone has put on. Is there a caliper upgrade for these forks, reason I ask is that I’ve read reports that some prefer to put 4 pots on over the 6 pots. Should I go back to k1 750 calipers or is there a good aftermarket caliper? All options are welcome. Thanks Alex.

Hello all. I have a bike that runs 12-13 all the way through the Rev range (road use) what af are you guys running on your turbo bikes? Have been told that 11-12 is better on these. Thanks Alex.

thanks all for your help today, much appreciated.
