Breaking down during an epic 5000km trek across India on a 145.5cc rickshaw might be a concern for some.
But Sol Hessell and James Bowen have had specialist motorcycle mechanics training from Antony Gibbons at Paragon Motorcycles.
Somehow, though, they're not quite sure they're prepared for the worst, considering their education has
consisted of "23 years of mechanics experience imparted in one hour, over a couple of beers".
The two Wanganui-based elements of the Three Muscatuks approached Mr Gibbons, co-owner of Paragon, for pre-race help. As his business is a client of Markham's Accountants, where Mr Bowen works, he was happy to oblige.
"We went over the basic principles of a two-stroke engine last Monday evening, using the Yamaha Ag-100 as an example," Mr Gibbons said, "the engine has the same configuration as the one on the tuk-tuk the boys will be riding across India".
A technology, he says, that hasn't changed since the 1970s, and one he assures is reliable.
"Basically, the lads should now be able to sort any minor problems they might have, or at least identify them."
And hopefully that's all the knowledge they'll need.
Mr Hessell and Mr Bowen are in the final stages of preparation for the 5000km, two-week race in April, and they've just been through a gruelling four-week-course of immunisation. They are now invincible against a host of diseases including rabies, hepatitis A and B, typhoid, cholera, diptheria and polio.
They have come up with £735 ($1596) of the £1000 they must raise for the International Rescue Corps charity in order to enter.
Mr Hessell has already flown out for some pre-race travel. He and Mr Bowen will meet up in India. Mr Hessell was one of many made redundant after the NZ Transport Agency decided to disband its Wanganui branch.
