Yes it’s over bored to get it up to 436cc apparently.
Have tracked the model & year of the 2A7 piston to 1977 `DT175 .

Re: The RD400 drag bike
Oh that’s a shame Al, my RD400 had a partial seizure last time out, but I haven’t investigated it yet. However there is a guy called Mally on the RD400 forum hat had issues similar to mine and it turned out to be aftermarket pistons that expanded too much as it was poor quality. So if you find the ...

Re: The RD400 drag bike
Well that’s a huge step backwards! With the 1st drag outing less than a month away, I thought i would start her up, get her up to temperature and make sure all the basics are still working. After wam up, did a couple of hard starts from about 3 to 4000 revs just to see it it wheelies or spins (it sp...

Re: The RD400 drag bike
Chaingaurd is required as part of the regulations for the straightliners organised drag events. Looking at the one on my firestorm, i thought it could be a good starting point to fit the RDs braced and extended swing arm, so I contacted Frank & Mac inc, and got a spare one. Some Dremel cuts a ta...

Re: WSBK 2024 RI.
Wow, that brought up some great racing.
Good to see at least 2 of the old number two riders in last years factory teams coming to life, now they are not in the shadow of the big star who used to take all the attention on the other side of the garage.

Re: Hello Again!
Not sure what it is that makes this Forum one of the best on the internet, but it might just be the type of people that the Firestorm attracts ….. they are a bit more genuine (less of a W@nker) than the average keyboard warrior type that are on other groups. Based on that I recon you should stay :th...
