HELP!! I need a 400rr parts connection

racer873 · 05-07-2008, 11:35 PM

I recently bought a non running cbr400rr for a project bike. I pulled the motor to determine what was wrong and discovered the previous owner had put the cams in backwards! they also broke one of the caps that secure the cams. I have a couple of questions. First can the cam retaining caps be purchased seperate or are they machined matched to the head? where can I get these parts? If I need a complete head assy where do I look for that? Since these bikes were not imported to the US my Honda dealer said they can't order parts for me.

Welcome aboard racer873. Sorry, but not living in the US, I don't know which direction to point you in. However, there are guys here from the US (One's in Florida) with a 400rr) so they may well be in a position to help.

Try David Silver spares here in the UK, according to their website they do send parts internationally and they may be able to advise you of what you need. You can email them and ask..

I hope you've gotten this sorted.
I have a spare set of cams if you still need them (stock). new they are about $250 each.
The cam towers are an issue as they are machine matched to the head. This is for both proper clearance around the cams (uses an oil bearing) and for the alignment of the oil passages, so... you really need a matched head and cam towers...

The cams can be broken very easily upon removal and / or installation. You have to tighten and loosen them very evenly. When loosening, sometimes I have to tap the towers lightly with a wooden dowel to "pop" them loose after I've just loosened the bolts a turn or so.
When tightening, just make sure you run down the bolts verrry evenly.
Yes.. I learned this the hard way.

O, and I have a friend coming over from Lincoln (Uk) end of August (I think). if you need a head and can wait, I can prolly talk him into stowing it in his bags. They are pretty light.
If you need other stuff, I can ask him to bring other stuff over too.

I have hookups on OEM parts and I had a CBR400RR, I also have the factory parts books for the CBR400RR and CBR250RR, let me know if you still need help. David Silver spare is expensive.

I also have (in uSA) original parts books, parts fiche on PDF, HRC set up book in print and PDF and haynes service manual on PDF.
I've had some of the HRC book translated. Everything is in Japanese except the haynes manual.

Thanks for the additional help guys. Wally I think the cams are ok its one of the cam caps that is the problem. The previous owner was careless and broke the oil passageway on one of the caps. I have a local machine shop that is appempting to repair it but if it doesn't work I will need a replacement head. I will PM you my number as I would like to discuss getting some parts through your friend.
CBR400rr the part I need at the moment is a head gasket. I will also PM you my number any help is appreciated

Did u know @ cycleimportsfl.com ? They mainly sell grey market bikes such as yours. Plus they're based in Florida. U can email info@cycleimports.com w/ any questions @ ur cbr400rr & they'll try to help u out, including getting parts.

racer873 · 06-22-2008, 12:03 PM

Yeah I know Ozzy and spoke with him a little about parts but he mainly deals in Grey bikes not parts and accessories. Sometimes he will make an exception if you purchase a bike through him though. Thanks for looking out !
