Re: Hot crank

Just to cover my options if I were to choose a 62mm crank other than a packer plate would I need to retune the barrel, machine the head etc? Please excuse my ignorance on the subject!

Re: Hot crank

I'm thinking about a 62mm replacement for this crank. Take the opportunity to try something new. I assume that will require a packer plate and some machining to the crankcase but is there anything else I should know?

Re: Hot crank

Thanks Rich. I was hoping you'd see this! Do you think I'd be better changing the crank altogether? I had been thinking about one of yours. Do you do a 116 rod?
To answer your question I do believe there is more vibration now but I ride this everyday so these things can go unnoticed.

Hot crank

Stripped my RB20 motor to sort a drive side oil seal and found the crank like this. There are no obvious signs of abnormal wear but I'm thinking that whatever caused the heat may well have ultimately caused the seal to fail. The crank has been in there for 3 years and was ok visually earlier in the ...

Re: rb200 pm fat mamba

I've been using one of late having borrowed one off a mate. Pleasantly surprised with the strong mid range. I don't think the top end is as good as the Franspeed race that it replaced but it is fun!

Re: Pipe Design Exhausts

I'm going to ask the person who paid for it on her credit card to see if she can claim it back in some way. I don't think she was aware that pipes were not in stock. I think she wanted to give me the choice. Marco told me that no money normally changes hands until a pipe is built which would be in k...

Re: Pipe Design Exhausts

Thanks for your replies guys. I spoke to him back in February to discuss the possibility of an order. As a gesture my mates cottoned onto this and obtained a voucher. I don't think it's fair to call that naive after all no seller will send you anything until it's been paid for. We all just expect to...

Pipe Design Exhausts

Does anyone know if Marco is operating at present? I ordered a pipe from them in June and was in regular e-mail contact with him up until late July when he told me he was building my pipe at that time. I've since heard nothing and not received the pipe either. I know they tend to take August off on ...

Re: Can't slow tickover down TMX38

I have a mate who has offered me his slide to try so thanks for that Martin. Maybe I'll have to shell out for a new one. I'd be interested to hear how the power jet carb runs on the RB. Someone suggested using a Thunder Power Jet from the US. They are easily adjusted by a knurled knob. Not heard of ...

Re: Can't slow tickover down TMX38

I think I've convinced myself it is the slide as when I partially obscure the cutaway or press the slide inwards it does slow down. Strangely enough as I wound the throttle stop screw inwards (to raise the slide) it also slowed it down a little. Seems if you manipulate the slide in some way it affec...
