Title: VG 414 restoration
Post by: cappra on June 02, 2010, 05:49:30 am
After a two year delay, I have decided to renew my VG 414 project.  I have reinstalled the motor, hooked up the electrics, relaced and trued
both wheels and will get tires mounted this week.  As you know the 414 motor never came in the VG 250 frame, so the pipe will have to be fabricated,
as well as the head stay (see pic)  Will also have to figure out what shocks to use and the footpeg mounts might have to be altered, as the seating to shifter,
brake pedal relationship feels wrong.  I want to have it ready to race by Sept.  Stay tuned.

 Very nice Jared. Is that the 250 VG that you were doing or another frame all-together? I'd love to put one in a H7 frame..... ;)

It was the VG 250 that I was going restore back to original, but thought what the heck, lets make it a racer instead of a hanger queen!

Did the VG 250 have the 'different' front braking system or the conventional front hub (what appears to be on that bike)?

Hmmm, yummy (http://i323.photobucket.com/albums/nn458/mx250syd/icons/drool.gif). Looking good 8).  Should be interesting to hear your ride impressions when it's finished ;) :D.

The VG 250 had the conventional front hub (VR/VB/VE) with a front pull brake lever.  The VG 414 had the different larger front hub, which was almost two
lbs heavier!

That would be the asymmetrical monster. Obviously introduced to improve braking power pre-disc and in competition against the TLS of the time. I didn't know it came with a 1 kg weight penalty  ::). It would be interesting to try and experience any braking performance improvements. And the increased weight effect on the suspension performance.

Hopefully I will be able to tell you in a few months if the large hub brake is any better.

That bike will be a weapon as the 250 H7 handles great. Steering feels much sharper than the VB-VF series although they handle great as well. It has just moved the H7 up to date with its peers of the time '82-84.

Jared the rear shock geometry is the same as the '81 Maico 250/490. I purchased piggy back YSS shocks for my H7 and when I sent in all the measurements they just supplied me a pair of shock set up for a Maico. Looks like Montesa may have looked around for the best set up they could adapt and went with it. Shhhhhhh don't tell those Maico people they may think its some form of a compliment ::). Bit the same as the reed valve block on the 250 H7 is KTM (again) Shhhhhhh

The VG250 has the large asymmetrical rear hub right?

If anyone has a VG Cappra white tank laying around (Ross??) I would love to replace the yellow VF style on my Pommy VG414 ;D.

My mistake.  I meant to say that the VG 250 white tank is tapped for the right side petcock only.
Exhaust pipe goes right under where the left side petcock would go.

This is a photo of an H7 360 enduro converted to a VG "360".  The rear loop was modified, all the various brackets were removed, pipe was gutted
and a VG 250 tank was fitted.  He is still running the H7 front brake setup.

Very nice indeedy.
I'm often tempted to take to my H7 with "the wheel of love" and do a similar conversion. God help the night I have one too many "Bonnox's" and I will (but I'll hate myself in the morning.... :'()

This is exactly what I plan to do with my 360 H7. We do not have any vinduro events in South Africa so I will use it as a pre-85 contender in the national VMX races. But I think I'll keep the blue seat! Mine also have the front disc which I will keep. Let me also add that I did buy it in a shocking state so I basically have a frame, wheels and engine to work from.

Update.  Fox shox's are out being rebuilt.  adjustable footpeg mounts being made.
Still working out the details of the pipe.

No Works Performance!??

The US versions of the VG 250 came with Fox shoxs, and everyone told me how great
they are, (all the Honda guy's wanted to buy them)  so I thought I would give them a go.

Wow! How do you get access to the filter? I take it that is the standard VG 250 air-box....... :P
Title: Re: VG 414 restoration
Post by: cappra on December 07, 2010, 11:51:21 am
There is a Uni Pod filter attached to an aluminum sleeve which is attached
to a rubber connector that fit's over the 38mm Mikuni.  Rear splash guard
must be removed to gain access to the filter.  The two top screws are removed
and the entire airbox is slid out the back, while the filter remains attached. 
 It's the standard VG 250 airbox, but I did add some vents to let in more air.

Almost complete!  Finish the footpeg mounts, pipe and get the seat covered.

Love the polished cases and the sand blasted head. Dainty little kicker, whats that off?

Title: Re: VG 414 restoration
Post by: cappra on January 13, 2011, 03:09:57 pm
Kicker is from a 83' Cota 349.  Not sure if it will stay.  Depends on how it kicks over...
Fox shox's me $300 to rebuild.  Hope it was worth it!

Looks cool with the Fox Shox Jared. ;) What did you do for a pipe?
I'm afraid anything other than the standard 'cave man' kick starter just looks outa place on a Cappra.
Very nice JB.... :)

Still working on the pipe.  Using a much modified VF 414 pipe.  cut, fit, cut, weld, cut, cut, fit, weld!
The VG 250 frame never came with a 414 motor, so it's a franken monty.  I did make sure not to change
anything that I can't undo to return it back to original 250 trim.

Beautiful job Jared 8). The polished side cases look excellent but will probably be a nightmare to keep that way? Have they been clear coated?

My Cota 350 had the same kickstart lever . It allows you to kick past the footpeg but I found it very slippery as you sort of kick at an angle and if your foot slips off then your calf muscle cops it  :'(.

I often wonder why Montesa did such a major update to the VG250 but left the VG414 very similar to the VF. The VG250 kept the same old front brake but the 414 got the very large but effective asymmetric job and the H7 series got the asymmetric rear brake ???  :-\.

As I said beautiful. 10 out of 10

Jared have you had to cut the head fins down to get the pipe to fit between head and frame/tank,the one i have which is the 250vg frame with a 414vg motor in it(Big flywheel = lots of torque brill) the head fins are cut down on left hand side to allow pipe to fit the pipe is a 414vg one cut to fit(this was already done when i got the bike). The shocks on mine are the original Betors and i must say work great the guy that serviced them said they were like an ohlins copy internals.Where can i get the air filters for it from.

Your bike looks great.
Title: Re: VG 414 restoration
Post by: cappra on January 27, 2011, 10:54:42 am
Will know by this weekend if the head fins have to be cut. 
Can't say about the air filter.  I'm using a different setup
than original.  I think Solo Montesa (yikes) has the oem filter.
I would have used the stock setup, but I have fitted a Mikuni
which has a much larger opening than oem Bing.
