Happy to answer any questions

Hi,
I was asked by another member if I would put some info on here about the exhaust on my bike, so here goes...

It's a Marving 4 into 1 race system bought from Wemoto.com about 18 months ago for £260.
Although its described as a race system it is not overly loud and has gone through 2 MOTs with no problems. It has a deep tone to it and only really turns up the volume when you open the throttle wide. Around town it isn't antisocial.

The system comes in one piece. You need to use your own exhaust clamps and collets and you have to fit the baffle in the silencer. The baffle and the cover for the end of the silencer are held in place by Allen bolts (supplied).

The system allows access to the oil filter and the downpipes follow a "standard" layout rather than the original systems swooping lines.

I haven't had the pleasure of riding a standard bike to compare with as mine came with a rotten hacksawed Marshall exhaust and I carried out a couple of mods on the carbs when rebuilding the bike.
Jets are one size larger, and needles raised one notch. The bike pulls well through the rev range with no flat spots. Occasionally as the throttle is cracked open there is a wooly feeling to the response but with a more positive wider opening this doesn't happen. I think this is more an issue with my carbs rather than anything to do with the exhaust.

After 18 months of mainly fair weather riding but a couple of times in the wet the chrome is unmarked. The only part of the exhaust that lets it down is the collecter where the down pipes join the silencer link pipe. For whatever reason this is not chromed but is hand painted with what looks like aluminium paint. Other welds at the end of the silencer are chromed and show no signs of corrosion.

Hope this is of use to anyone considering buying a Marving pipe. I've no regrets.

I am in the process of respraying the tank and panels of my 400 and noticed on the decals I have from David Silver that there is a spelling mistake on the safety decal that sits in front of the petrol tank filler cap. It says 'Think saftey' rather than safety.
My question is whether this is a mistake on the part of whoever made the repo decals or if it is an intentional copy of an original Honda mistake.

Just curious

Hi.
Like some others on here I have just found the UK site after browsing topics on the US site.

I've been biking in one form or another for the past 26 years but have had only a small number of bikes in that time - I've had my GSXR since 1997 and before that had a KR1S, FZR600 TZR250 and a Honda Express(!). I also had a 2003 Z1000 for a couple of years.

I bought my 400/4 in October 2011. It hasn't been on the road since 1988 but between then and now had undergone some restoration by the previous owner. He replaced the rims and spokes with pattern parts, shocks (Hagon), had the frame resprayed and had overhauled the carbs and ignition. After that he lost interest and the bike had sat in a barn for another 4 or 5 years. I bought it (with some haggling) for
