Is the rectifier the same as on the Honda CBR400RR to the CBR900RR. The numbers on the top tally and the shape is the same....just the two small
numbers beneath dont. Mine says 2.5 and the 4ooRR says 5.2.
Could do with some verification before I buy.
Been quoted £115.00 + VAT for a new one from Honda........bugger
not 100% sure on mix n match on these but Chris will prob know, but £115+ is a bit ott, will search out reciept for last one i bought, seem to remember under £50 posted to me, will look out and post supplier's addy 4 u.........
i got a new rectifier for me vtr1000 b4 i sold for about £60 think it was from here
just looked, they are £64.95 inc vat
thats a bit better, thought it was a bit steep
Has anyone thought of making there own rectifier and voltage regulator as a heavy duty replacement for bike ones?
The rectifer section would cost very little and the main problem would be deciding what type of voltage reg chip to use to sink the neccesary current,
as the bike alternator unlike a car always delivers full current regardless of demand which is why bike regs are known for overheating and burning
out.

I was thinking of doing my own regulator because I'd like an electrically heated screen... think this might tax a bike rect/reg a bit.
They're simple enough to wire up - 3 phases in, + & - out.
I notice pictures of these things on folks websites just stuck out of the way onto fibreglass - ouch hot hot hot - I'd suggest they should be
somewhere cool bolted onto metal for extra heat sinking - preferably not next to the engine or exhaust; in front of rad sounds good if possible
too.....

PS DIY can improve efficiency by spending money on oversize mosfet and shottkys + stick on a bigger heatsink etc. But I'll see how the stock item
gets on first,
Thanks for the vote of confidence Jon......but I dunno Im afraid 
Kitcar workshop were doing some uprated ones for £120 or so, but like others have mentioned, pattern replacements are usually around £60 or so.
Its all about keeping it cool to make them reliable tho, if they arent kept cool they will fry pretty quickly.
Some recommend strapping it to a big lump of ally to act as a heatsink but I used an old Athon CPU heatsink and rigged the fan into the ignition, and
thats kept it very cool and reliable for over 2 years now.
cheers
