I will had photos when im next in the workshopYes it was thank you for your responce ive now brought a the proper bolt that should be on the cam chain but thank you so much for the help and advise
I have a cx500 e trike from 1982 im in tamworth staffordshire
As you can see in the pic they put any bolt in the camshaft tentioner on the inside the case then they siliconed the hole up and stuck a coin it there to stop the oil comeing out but im going to restore the engine to how it should beThe engine is out the bike and in bits the person i had it of was very handy with silicon seal not gaskets so im putting the engine back as it should be View attachment 210757
Yea they also try to use the silicone as head gaskets ence the compleate stripdown but thank you so much for the advise and helpSounds like a worthwhile project. Silicone sealant can be used to augment gaskets (except head gaskets) but it is never an acceptable substitute for them.
It looks like the PO tried to use a plain M6 bolt there instead of the correct one. Who knows what else you'll find....
The frame is also a cx500 and the engine belongs to the frame ence the back end now has a reliant back axel on it to turn it in a trike and its been like that since 1984Do you mean that the trike has an engine with serial number beginning CX500E- ? That is a different beast than a CX500E. See here for a list of frame and engine numbers. Honda CX400 and CX500 Engine and Frame Serial Numbers
Yes the numbers all match the paperwork it is also reg as a trike not a Q plate the orignal bike was a candian import in 1980 and it was re registered in 1992 by the dvla and everything matchThere are a number of CX500 models and there were some changes between the years of some models so it is important to figure out the correct model and year that the bike started life as.
Does your UK paperwork show the engine serial number as well as the frame number? If the records don't show the engine number the original engine could have been replaced with one from any of the CX500 variants at some time in the past.
CX500 engines came with serial numbers beginning with CX500E-2000001 for the first one produced in 1978. The first year for the CX500E (AKA "Sport" or "Eurosport") was 1981 and the engines in them started with number PC02E-4003828.
Things become even more complicated by the fact that UK vehicle paperwork shows the year first sold, NOT the model year. Because of that the dates in vehicle papers are often several years later than the actual model year. This can make finding the correct parts very confusing.
All of that said, the engine you posted a picture of has Capacitor Discharge Ignition (CDI) but the CX500E came with Transistor amplifier Ignition (TI, sometimes called TAI) so that is definitely NOT a CX500E.
I would suggest looking up your frame and engine numbers at the page Reclinedrelic posted the link to so that you can find out what it actually is.
Fiund the problem thanksYah that bolt profile suggests a issue.
...u wont know til you delve further in.....best o' luck.....👍
I know it went to a dvla test center to be checked and came back out with the proper paperwork i must had not a mot center that was all done before i had it the chap i had it off was disabled rider which is what i am i know its all legal in the ukIf it was imported from Canada there should be a plate attached to the steering head that has the VIN plus the model, model year and date of manufacture (they were usually manufactured in the last quarter of the year before the model year).
And if it came from Canada it is definitely not a CX500E because Honda Canada didn't import any of them (not to mention that they weren't made for the 1980 model year.
Thats how it is ive just brought the proper bolt and seal for it just waiting for it to arrive so i can do itI think the PO actually had the rear cover off and used a standard screw/bolt to tighten the tensioner and then put the rear cover back on. At least that's how it looks.
Just waiting on the origanal bolt and seal to arrive the i will seeI think that it looks like the hole may have been widened? If so a rear cover would be needed to work with the proper bolt.

Its a Cx500E acording the the markings on the engine and they match the logbookSo UK paperwork aside, what model and model year is it really (according to the plate on the steering head)? That is what you will need to know to get correct advice on keeping it running and for getting the correct parts to fit it.
